Brief summaries of this weekend's new movies, including "Captain America" and "Friends with Benefits."

CAPTAIN AMERICA: THE FIRST AVENGER


That’s Chris Evans behind the famous shield, as Marvel brings one of its most popular comic book heroes to the screen. In what is billed as yet another “origin” picture, director Joe Johnson (“The Rookie”) shows us how weak, ineffectual Army officer Steve Rogers transforms himself into the world’s most famous superhero after he’s selected for a top-secret research project. Stanley Tucci, Tommy Lee Jones and Hugo Weaving co-star.


BEATS, RHYMES & LIFE: THE TRAVELS OF A TRIBE CALLED QUEST


Actor Michael Rapaport directs this tribute to the influential hip-hop band, which enjoyed several years atop the music charts before suddenly disbanding in 1998. Rapaport, one of the band’s biggest fans, chronicles the Tribe’s 2008 reunion tour while examining how the band was initially torn apart and how their personal differences and unresolved conflicts continue to be a threat to the band’s existence.


FRIENDS WITH BENEFITS


Mila Kunis, hot off her steaming lesbian sex scene in “Black Swan,” goes straight for Justin Timberlake after she decides she wants to hook up with a male sex partner disinterested in forming emotional attachments. If you’re having a moment of deja vu, it might be because Kunis’ “Black Swan” bedmate, Natalie Portman, starred in a similarly plotted movie just six months ago called “No Strings Attached.” Well, at least now we can compare to see which actress makes her male lover happier.


SNOW FLOWER AND THE SECRET FAN


Wayne Wang (“Joy Luck Club”) directs this film version of Lisa See’s best-selling novel about parallel female friendships, one in the 18th century and the other in the 21st.


THE TREE


Brit Charlotte Gainsbourg stars in French filmmaker Julie Bertuccelli’s Australian-set mystical drama about a widow and her four young children, who believe the spirit of their late father lives on inside a tree next to their outback home.
