Everyone who pledges $5 or more will get in the end credits, beneath 'Special Thanks.'
Why not make up a story to your friends about how your special thanks is for pointing out that whole 'lens cap' thing?
At least five livestreams spread from pre-prod to post, protected by password (or link only) and unlisted, each an hour long. Georg will answer questions from the chat, and maybe waffle on like an eccentric mad man. Might not be on YT, depending on the whole copystrike thing.
Access to a stream of an early (but narratively complete) cut of Collaborator, and chance to influence any reshoot or edits.
There'll be a form to fill in and your feedback will not only be processed, but even greatly appreciated. You'll have to get your own popcorn though. There'll be a Q&A on the same stream after. Please keep in mind the project will still be a work in progress, and will probably have to be streamed in 1080p rather than 4k.
