“You’re a... teacher?” “Part-time.”

Summer movie season, here we come. Ahead of its release on Memorial Day weekend, the first trailer for Indy 4 (OK, fine—Indiana Jones and the Kingdom of the Crystal Skull. Blech. That title sucks.) made its way to the InterWeb this week. As expected, it looks action-packed, and I appreciate the willingness to crack jokes at the expense of Harrison Ford’s age, but there’s a few things that worry me. I’m remaining cautiously optimistic, but that shot of a car chase along the edge of an obviously CGI-created cliff is concerning. One of the greatest things about the original trilogy is that the locations were always real, and the stunts always looked like they could actually happen. George Lucas’ obsession with computer-created movies better not ruin this franchise too.

But as long as this movie remains firmly focused on Indy as the main character, and doesn't just become a setup to extend the franchise with Steven Spielberg’s boy-crush Shia LeBouf, I'll be happy. Something else that makes me happy is that Karen Allen’s character Marion Ravenwood from Raiders of the Lost Ark is back. You can see her briefly in one shot, but she’s such a great character, I’m surprised they didn’t play up her return more. Maybe in the next preview.
