It's awards season which means, among other things, that those in the movie industry must smile and make nice with their enemies and competitors while cameras are rolling. We all saw the nominees' thin, tight-lipped smiles as host Ricky Gervais roasted them at this year's Golden Globes ceremony. What else can they do? The world is watching.

However, on the movie set, it's a different ballgame. Actors and directors may say everyone was a joy to work with during interviews. However, tensions run high on-set and creative types can be explosive by nature. The film set is where bridges are burned and arch-nemeses are made. As proof, we look at the 10 most-explosive on-set fights (that we know about).

Sarah Jessica Parker vs. Kim Cattrall

After a dozen years of working together on the HBO series and first movie, Parker and Cattrall finally became fed up with one another during the filming of "Sex and the City 2." Rather than pulling each other's hair out, they chose the Cold War approach of no communication, veiled threats and talking sh** behind each other's backs. That can be even more uncomfortable than a screaming match -- at least that doesn't last for months.

Debra Winger vs. Shirley MacLaine

"Terms of Endearment" chronicles the emotionally taxing relationship between a mother and daughter over several years. The tension between 49-year old MacLaine and 28-year old Winger didn't end on-screen. The conservative MacLaine hated Winger's erratic behavior and vice versa. Reportedly, Winger once lifted her skirt and aimed a fart toward Maclaine. Winger later told interviewers: “"There was no blood drawn. There might have been a scuffle. I don't remember. I mean, we were wild, you know."

Lily Tomlin vs. David O. Russell

After the release of 2004's "I Heart Huckabees," an outtake of actress Lily Tomlin and director David O. Russell engaged in a screaming match began circulating around the Internet. "The Fighter" director has a reputation for being a hothead, but claims he was intentionally trying to destabilize the actors to improve their performances. That's an interesting tactic for a comedy. Intentional or not, Tomlin later said they reconciled: "I'd rather have someone human and available and raw and open. Don't give me someone cold, or cut off, or someone who considers themselves dignified."

Hardcore actors Daniel Day-Lewis and Christian Bale are known for staying in character, even off-camera, through the entire filming process. Add LL Cool J to that list, because on the set of "Any Given Sunday," he continued to fight Jamie Foxx after director Oliver Stone called cut. Foxx even called the police and filed assault charges, while LL claims, "It wasn't Jamie and I fighting. It was our characters." The two reconciled seven years later, in 2006, and Foxx performed on LL's album, "Todd Smith." Foxx even wanted to be LL's hypeman.

Dennis Hopper vs. Rip Torn

Eccentric actor Rip Torn, known for his Academy Award-nominated role in the 1983 film "Cross Creek" and his role on "The Larry Sanders Show," was originally cast in Jack Nicholson's role of 1969's "Easy Rider." Thirty years later, the movie's director Dennis Hopper told Jay Leno on "The Tonight Show" that the recasting occurred after Torn had pulled a knife on him during a vicious argument. Still sore on the subject, Torn filed a filed a defamation lawsuit against Hopper, claiming Hopper had actually pulled the knife on Torn. Either way, not the easiest Rider.

Klaus Kinski vs. Werner Herzog

Actor Klaus Kinski and director Werner Herzog became best friends after working together during the '70s in Germany. Herzog even called Kinski his muse, casting him in five films. Kinski was known as a manic, wild-eyed, sex-crazed nut-job and died of a heart attack in 1989. Ten years later, Herzog released "My Best Fiend," a documentary about their volatile yet productive relationship. The film includes plenty of crazy Kinski footage, including this heated fight on the set of 1982's "Fitzcarraldo."

In bored moments, you may have wondered why Bernie Mac replaced Bill Murray as Bosley in the sequel, "Charlie's Angels: Full Throttle." It's reportedly due to a fight the comedian provoked with Lucy Liu on set of "Charlie's Angels." The story is Murray stopped a scene, pointed to Drew Barrymore, Cameron Diaz and Liu, and said in order, "I get why you're here. And you've got talent. But what in the hell are you doing here? You can't act." The "Kill Bill" actress flipped and began showering Murray with punches until crew members separated them.

Christian Bale vs. Shane Hurlbut

You may not be familiar with Shane Hurlbut's name, but everyone is aware of Bale's verbal tirade on the set of  "Terminator Salvation." Hurlbut is the man he's assaulting with profanities. Bale claims Hurlbut, the movie's director of photography, had twice broken his concentration by walking on set during a scene. Bale ended the vicious diatribe by threatening to quit if Hurlbut repeated the offense. In case the actor made good on his promise, Warner Brothers executives sent the tape to the film's insurer, who must have leaked it. That is why we have countless jokes, parodies and the song "R U Professional" by The Mae Shi.

You already know David O. Russell is a hothead, but in 1999 he was in over his head as well. "Three Kings" was Russell's first big budget film and the studio gave him constant headaches with their notes and worries, turning him into a beast onset. Clooney took it upon himself to defend crew members and extras against Russell's outbursts. Tension between the star and director culminated in a physical brawl where Russell head-butted Clooney... and then they choked one another.

Rip Torn vs. Norman Mailer

After gaining fame as a novelist, journalist and all-around tough guy, Norman Mailer decided to become an avant-garde filmmaker as well. In 1970, he cast Rip Torn to star opposite him in the heavily improvised "Maidstorm," a movie about a famous director (Mailer) who runs for President and his freeloading brother Raoul (Torn). As cameras rolled, Torn decided to "improvise" a brutal fight and hit Mailer in the head with a hammer. Despite a nasty head wound, Mailer fights back by biting off a chunk of Torn's ear. The battle continues until Mailer's wife and wailing children break it up. Even though the "actors" use each others' real names, the scene was included in the film.
