It was a busy week for the Motion Picture Association of America's Classification and Ratings Administration, as they issued new ratings for Tron Legacy, Little Fockers, The Warrior's Way and many more. Also, their weekly bulletin finally included the controversial NC-17 rating for Blue Valentine, which is currently being appealed by The Weinstein Company.

Tron Legacy received a PG for "sequences of sci-fi action violence and brief mild language." That's the same rating as the 1982 original Tron, though the PG-13 rating wasn't yet in existence back then. The PG designation suggests that distributor Walt Disney Pictures plans to not only target fans of Tron and teenage boys but also family audiences throughout the holiday season. Starring Jeff Bridges, Garrett Hedlund and Olivia Wilde, Tron Legacy is set to open Dec. 17 against Yogi Bear, How Do You Know and the nationwide expansion of The Fighter.

Speaking of How Do You Know, the James L. Brooks comedy was edited and resubmitted after being slapped with an R rating at the beginning of the month. The MPAA deemed the new version worthy of a PG-13 for "sexual content and some strong language."

Little Fockers and Gulliver's Travels, both scheduled to face the True Grit remake on Dec. 22, were awarded ratings this week. Similar to the first two Meet the Parents movies, Little Fockers earned a PG-13 for "mature sexual humor throughout, language and some drug content." In contrast, Gulliver's Travels qualified for a PG rating for "brief rude humor, mild language and action."

The Warrior's Way was tagged with an R rating for "strong bloody violence." The fantasy western debuts next Friday, Dec. 3, at around 1,500 locations, and it's set to go up against the planned nationwide expansion of The Nutcracker in 3D and the likely nationwide release of 127 Hours.

Ron Howard comedy The Dilemma received a PG-13 for "mature thematic elements involving sexual content." The movie, which stars Vince Vaughn and Kevin James, has been plagued by controversy due to a purportedly homophobic line in the original theatrical trailer. The line has since been removed from the trailer, but Howard has said that it will remain in the actual movie. The Dilemma is currently slated to face The Green Hornet on Jan. 14.

Sanctum was rated R for "language, some violence and disturbing images." Produced by James Cameron, the 3D-illusion thriller opens Feb. 4 against The Roommate.

While the rating has been widely known for months now, the MPAA finally made it official: Blue Valentine garnered a prohibitive NC-17 rating for "a scene of explicit sexual content." In recent weeks, The Weinstein Company has assembled a team of lawyers to protest the rating in the hopes of having it reduced to an R, which will allow it to show at many more theaters nationwide. Starring Ryan Gosling and Michelle Williams, the drama is slated for a limited launch on Dec. 31.

A few upcoming limited releases were also given ratings this week. Barney's Version, which stars Paul Giamatti and opens Jan. 14, was awarded an R for "language and some sexual content." Rare Exports: A Christmas Tale was also given an R rating, though it was for "some nudity and language." Finally, Terrence Malick's The Tree of Life was edited and resubmitted, but earned the same PG-13 rating for "some thematic material." Rare Exports opens Dec. 3, while The Tree of Life hits theaters May 27.
