Zac Efron, Vanessa Hudgens, director Kenny Ortega and all of the other cast and crew of the first two "High School Musical" movies are back in Utah to film "High School Musical 3: Senior Year." Most of the cast is already in rehearsal, but a couple of very small roles are up for grabs.

Through Friday, you can snag "Musical" memorabilia in an online auction sponsored by Rowland Hall-St. Mark's School and the SLC Film Center, but the real prize is eight roles for extras in "Senior Year." That's, right, if you submit the winning bid, then you or your child will be in the cast, or, you know, at least in the background of that one scene.

The charitable auction is open to the public and can be found at www.cmarket.com/auction/AuctionHome.action?vhost=rhsm. As of Tuesday morning, only four of the roles had received an opening bid, and none of the auctions had moved past the opening bid baseline of $1,000.
