Best Bets on TV Tonight

Seeking to explain male behavior after a series of failed relationships, a talk-show producer (Ashley Judd) becomes a celebrity "expert" in "Someone Like You" (8 p.m., Fox). What does this mean for her chances of romance with her womanizing coworker (Hugh Jackman)? Greg Kinnear also stars in this 2001 romantic comedy.
The showing of the Oscar-winning film "A Farewell to Arms" (8 p.m., TCM) from 1932 marks the start of a Memorial Day movie marathon. Steve McQueen, John Wayne, Gary Cooper and Robert Montgomery are a few of the actors who depict men in the throes of war.
"Finding Nemo" (10:35 p.m., Starz) was last year's hit animated feature about family life in the world of fish. (For kids not allowed to stay up quite this late, the film repeats at 7 a.m. and 2:15 p.m. Saturday.) The voice cast includes Albert Brooks, Ellen DeGeneres, Brad Garrett and Allison Janney.
"Moulin Rouge" (midnight, VH1) is a musical about star-crossed lovers, set in the Paris of 1899 and co-starring Nicole Kidman. And as its struggling-writer hero, Ewan McGregor is required to sing such songs as Elton John's "Your Song," Dolly Parton's "I Will Always Love You," Sting's "Roxanne" and even a bit of Rodgers and Hammerstein's "The Sound of Music." McGregor meets the challenge by committing to the film as he has never committed to a film before.
