There are some really creative and interesting rewards for higher contributions. Personalized video message from the cast, personalized video message from Kristen Bell (much more expensive, obviously!), voicemail recordings, name a character after someone, have a local theatre rented out for a private showing possibly before the screenings, after-party tickets, be an extra, or even have a speaking role.
I presume that ultimate reward means this movie is outside the purview of SAG-AFTRA, as any speaking roles in SAG productions absolutely, positively must be performed by SAG guild members. This is going to be an official Warner Brothers product, and I wasn't aware WB was not fully in bed with SAG-AFTRA.
EDIT: What's up with Bell? She doesn't seem to understand the concept of Capital Letters aNd WHerE thEy bELONG In A Sentence. Or she's just being coy.
