Today in show business: Kevin Arnold is a big grownup success, Robert Redford joins the Marvel family, and American Idol is in trouble.

Fred Savage, little Kevin Arnold from The Wonder Years, is in talks to direct a movie starring Charlie Theron. Yes! He's been an in-demand TV director for a few years, and is now making his transition into feature films. The movie is Ladies Night, a comedy about a woman having one last night on the town with her friends before moving to New York City. Sounds like sort of a strange project for Charlize Theron — does she really have friends? — but hey, what the hell. Fred Savage and Charlize Theron hanging out together! That's quite something. Is he the new Ron Howard? [The Hollywood Reporter]

American Idol's ratings continue to drop. Last night's episode was watched by a measly 11.7 million people for a 2.8 rating in the 18-49 demo. That's down from an all-time high of 6.0. And it's dropping like this every week. So what's the problem? Bad contestants? Well, yes. General fatigue? Also that, too. It's a bad combination and the show is hugely suffering for it. Could this be the last year of American Idol? In some ways that prospect saddens me. In others it absolutely thrills me. I mean, the idea that Idol could go out with more people watching The Voice is an awful one, but no more Idol means I have my Wednesday nights back again. Back to watch other TV, but still back.

Game of Thrones author George R.R. Martin is going to make a Stephen King-style cameo on the show next season. One hopes, and assumes, he will be an employee in Littlefinger's brothel. [Deadline]

Robert Redford is close to signing a deal to star in Captain America: Winter Soldier, the Marvel sequel. He won't be playing the Captain, no that's still Chris Evans unfortunately, but he'll be a top guy at S.H.I.E.L.D. The movie will apparently focus on Captain America's "relationship with [his] sidekick Bucky," which... what kind of "relationship" are we talking about here? And when they say "sidekick" what do they mean exactly? Suddenly this movie got really intriguing. [The Hollywood Reporter]

Here is a trailer for Turbo, a movie about a snail. Because I guess there hasn't been a movie about a snail yet? The thing is he races, but he's super slow. Because he's a snail. Sure, why not.
