Funny fluff and a shocking documentary about the rough and tough are hitting theaters this weekend.

Reese Witherspoon's "Sweet Home Alabama" and the Jackie Chan/ Jennifer Love Hewitt action/comedy team-up "The Tuxedo" will open nationwide, while the decidedly more serious "Biggie and Tupac," a controversial documentary that takes a look at the unsolved murders of both rappers, will open in select cities.

"Sweet Home Alabama" is a light-hearted romantic comedy that centers on the "Legally Blonde" star as an Alabama gal who left behind her family and friends for a booming fashion career in New York City, where she gets engaged to a fabulous guy played by Patrick Dempsey ("Scream 3"). There's just one problem: Before she can get married, she'll have to finish getting divorced from the stubborn Alabama husband (Josh Lucas of "A Beautiful Mind") she left behind.

Jennifer Love Hewitt, who recently took some time away from Hollywood to complete a new album (see "Jennifer Love Hewitt Makes Rock Record, But Won't Be Doing Weird Hair Streaks"), gets a chance to strut her action/comedy stuff in a return to the big screen. "The Tuxedo" features martial-arts film legend Jackie Chan as a taxi driver who becomes a chauffeur for a secret agent. When that agent is wounded, Chan bumbles his way into impersonating him and following up on his latest case, aided by a high-tech, super-powered tux and a brainy but butt-kicking agent played by Hewitt.

In sharp contrast to the light tone of each of those comedies, "Biggie and Tupac" is a sober and often complex examination of the various facets of the ongoing investigation and speculation about the murders of the two iconic rappers.

"Biggie and Tupac" is comprised of a jailhouse interview with Suge Knight as well as chats with Biggie's mother and former LAPD homicide detective Russell Poole, whose Suge Knight-centered murder theory was also the basis of Rolling Stone writer Randall Sullivan's book "LAbyrinth." The film was put together by British filmmaker Nick Broomfield.

Broomfield, the man behind the "Kurt and Courtney" documentary that suggested that Courtney Love conspired to murder her late husband Kurt Cobain, conducts all of the interviews himself. He finished much of the film before the L.A. Times published allegations implicating Biggie in Tupac's murder (see "Biggie Paid Gang To Kill Tupac, Report Says").

"Biggie and Tupac" will open in select cities over the weekend, as will "Moonlight Mile," a drama starring Dustin Hoffman ("Rain Man"), Susan Sarandon ("The Banger Sisters") and Jake Gyllenhaal ("The Good Girl").
