An age-restricted trailer for New Line Cinema’s upcoming comedy Semi-Pro is now online at the movie’s official site.

To gain access to the R-rated trailer, you’ll have to enter your full name, date of birth, and zip code. If you can get in, I highly recommend you watch it, since it’s funny as hell. While the all-ages trailer allows you to get a feel for the movie (watch it here after the jump), it definitely suffers from flat-joke syndrome much like all those censored Superbad clips.

Semi-Pro, which stars Will Ferrell and Woody Harrelson, hits theaters on February 29, 2007. Synopsis for the movie is here after the jump.

Official Synopsis

Will Ferrell stars in Semi-Pro, an outrageous comedy set in 1976 against the backdrop of the maverick ABA – a fast-paced, wild and crazy basketball league that rivaled the NBA and made a name for itself with innovations like the three-point shot and slam dunk contest.

Ferrell plays Jackie Moon, a one-hit wonder who used the profits from the success of his chart-topping song “Love Me Sexy” to achieve his dream of owning a basketball team. But Moon’s franchise, the Flint Michigan Tropics, is the worst team in the league and in danger of folding when the ABA announces its plans to merge with the NBA.

If they want to survive, Jackie and the Tropics must now do the seemingly impossible – win.

Semi-Pro co-stars Woody Harrelson (Anger Management, White Men Can’t Jump), Andre Benjamin (Four Brothers, music group Outkast), Maura Tierney, Will Arnett (Blades of Glory, “Arrested Development”), Andy Richter, Rob Corddry, DeRay Davis, Josh Braaten, Jay Phillips, and Jackie Earle Haley.

The film is written by Scot Armstrong (Old School), directed by Kent Alterman, produced by Jimmy Miller, and will be released on February 29, 2008.
