Why are we still surprised to see Oscar-winning celebs in made-for-TV movies? They're no longer maligned as a medium for wannabes or has-beens, argues Diane Keaton. This Sunday, she stars in Crossed Over — airing at 9 pm/ET on CBS — the true story of Beverly Lowry, who came to terms with her son's death by befriending death row inmate Karla Faye Tucker (Jennifer Jason Leigh).

"The television movie has changed," says Woody Allen's one-time muse. "With serious television and HBO, I don't think there's anybody saying that one is superior to the other."

Keaton admits she's grateful for any role she can get in the increasingly ageist industry. With the exception of The First Wives Club — where she co-starred with Goldie Hawn and Bette Midler — recent baby-boomer films like her Town and Country have bombed. These days, Keaton frankly says she'll do "whatever is possible for me to play, considering my limitations. I'll do pretty much anything that has substance or is funny."

Keaton also keeps busy with her own production company, Blue Relief Productions, and a sporadic directing career. (There's also been talk of a First Wives sequel.) So the 56-year-old actress is rarely one to rest on her Annie Hall laurels. "When you're burdened with the responsibility to live up to what you've done, it changes the tone [of your work]," she explains. "Sometimes you just have this serendipitous moment, and Annie Hall was one of them, where it just came together."
