"30 Rock" star Alec Baldwin plays a hilarious, self-proclaimed "sex-crazed maniac masquerading as a college professor" in his new romantic comedy, 'My Best Friend's Girl,' in theaters September 19 -- and ET has an exclusive look! "I think my character is the single reason for the women's rights movement in this country," says Alec. "My character is the most disgusting, sexually selfish guy I've seen in a film in a long, long time. He teaches women's studies at a college, but at the same time he's trying to scam all the women, in the classroom and outside of the classroom." Alec adds that the loathsome character has actually improved his take on the better sex.
