The 2011 Sundance Film Festival kicked off today in Park City, Utah, and you've probably noticed that MTV has already been featuring clips and set visits from many of the fest's most anticipated flicks. Well, we've got another one for you, and it's a doozy: the trailer premiere for Sundance's big closing-night film "Son Of No One," featuring a stellar ensemble cast that includes Channing Tatum, Katie Holmes, Al Pacino, Ray Liotta, Juliette Binoche and -- in his first true dramatic role -- "30 Rock" funnyman Tracy Morgan. Check out the trailer below.

Directed by Sundance vet Dito Montiel ("A Guide to Recognizing Our Saints," "Fighting"), "Son of No One" follows two friends (Tatum and Morgan) forced to face the consequences of a murder they committed -- and got away with -- 16 years earlier. Tatum's character Jonathan "Milk" White has gone on to a successful career with the police force and has a happy home life with his wife (Holmes) and Child. Morgan's character Vinnie has kind of gone the other way. When Milk is assigned to the precinct where he grew up, his decade-and-a-half-old secret threatens to tear apart his life and his family.

The trailer looks pretty tense, and the casting isn't too shabby either. Plus, judging by what Tatum told MTV when we visited the "Son of No One" set this year, Morgan could be well on his way to earning the "O" (Oscar) in the EGOT (Emmy, Grammy, Oscar, Tony) that his "30 Rock" alter-ego is famously chasing. "I think Tracy Morgan is going to shock the world," said Tatum. "Nobody has ever seen him do drama or anything like that."

What do you think of the trailer for "Son of No One"? Are you excited to see Tracy Morgan in a dramatic role?
