Fans of the filmed-in-Oregon (and Washington) vampire movie "Twilight" have a chance Saturday to watch cast members play baseball at PGE Park, all while supporting the Make-A-Wish Oregon foundation.

"Twilight" was shot on-location around Oregon.

The event is called "Vampire Baseball" and depending on your contribution level, you watch just the mid-morning game, or make a day and night of it with a Portland Beavers game (actress Rachelle Lefevre throws out the first pitch) followed by Fourth of July fireworks.

Tickets to just the Vampire Baseball game are $45.

The  premium deal costs  $135 and includes the Vampire Baseball game, a lottery-picked fan game, one voucher for a cast autograph and a ticket and a meal to the Beaver game.

Those purchasing premium tickets can spend another $100 and move towards the front of the line for autographs. This also upgrades your game ticket closer to the field.  Limited slots for $149 each are also available for a personal cup of coffee with cast members.
