By now, there are certain things you know you'll see when "Spider-Man 3" finally swings into theaters May 4: Spidey will swing; Mary Jane will scream; and Venom, the new Goblin and the Sandman will wreak havoc on Peter Parker's life.

But wait until you get a load of what else director Sam Raimi has in store for his signature superhero franchise (see "Tobey Maguire Dogfights With James Franco In New 'Spider-Man 3' Clip"). MTV News is one of the few outlets in the world that has seen the top-secret movie, and here's a spoiler-free (we promise!) guide to the Spidey moments most likely to raise some eyebrows.

S-s-s-smokin'?
One sure-to-be-controversial moment is a dance sequence that plays like a deleted scene from the Jim Carrey flick "The Mask." Kicking up his heels at a jazz nightclub, a suddenly smooth Peter Parker (Tobey Maguire) uses his superpowers to leap into the air, tickle the piano keys and persuade those around him to snap along to the rhythm. While "Moulin Rouge" fans should find it thrilling, hard-core geeks might want to schedule a bathroom break in order to keep their blood-pressure levels manageable.

Kiss Kiss, Bang Bang
Arguably the most famous moment in the "Spider-Man" movies is the upside-down kiss between Peter and Mary Jane (Kirsten Dunst) in the original flick. Look for that iconic moment to be turned on its ear in "3" — with a decidedly less-romantic result.

Songs Sung Blue
While the other films have shown Mary Jane working her way up the showbiz ladder, "3" makes it a point to have the leading lady expressing herself in song. From the Broadway stage to the aforementioned nightclub, Dunst displays her singing voice enough times to turn "3" into a near-musical, with each tune (including standards like "They Say It's Wonderful" and "I'm Through With Love") corresponding to her mood at that point in the story. As for the actress's voice — is it live or taped? You make the call.

30 Seconds to Marvel
While it's no secret that wearing the Venom suit takes Peter to some very dark places, you might be surprised at how such evil leanings are expressed. Maguire's hair not only seems to turn blacker in each scene, but as it grows down over his eye and is parted to the side, one can't help but notice his sudden resemblance to Jared Leto. Add in what appears to be some eyeliner, and you might expect Maguire to turn to the camera and start belting out "The Kill."

The Scene Stealers
You might be paying your $10 to see the big names, but some of the most memorable moments come from veteran actors in expanded roles. Raimi loyalists will be geeked to know that Bruce Campbell (the "Evil Dead" films) gets the biggest laugh of the film as a snooty maitre d' at a French restaurant, while John Paxton's three-movie arc as the Osborns' butler finally pays off when he delivers one of the film's most pivotal lines. Dylan Baker's Dr. Curt Conners receives such ample screen time that it seems to guarantee he'll make the full transformation into the Lizard in an upcoming Spidey flick, and "The 40-Year-Old Virgin" actress Elizabeth Banks gets surprisingly intimate with Maguire — appropriate, since her character, Daily Bugle secretary Betty Brant, dated Peter in the comics (see " 'Spider-Man' Secretary Dishes On Hero's Hookups, Black Suit").

Stan Lee: Oscar Hopeful?
While Marvel Comics has made a wonderful tradition out of giving legendary comic creator Stan Lee a cameo in virtually every one of its movies, his appearance in "3" makes the greatest emotional impact. Stepping up alongside Peter, the 84-year-old "Spider-Man" co-creator delivers the line "One person really can make a difference." He then punctuates it with his classic sign-off: " 'Nuff said."

No Secret, No Wars
While the origin of the suit that eventually becomes Venom (Topher Grace) is the most notable departure from the "Spider-Man" comic books, Thomas Haden Church's Sandman has also had his back story significantly altered. Look for the former to be much more controversial than the latter.

Twisting the Night Away?
Believe it or not, one of the film's most memorable scenes involves James Franco and Dunst dancing together to the 1960 Chubby Checker classic "The Twist." Yup, you read that right.
