Here's an odd one...but I'd finish the series ALF. It had an opening season ending...and was never picked up for another season.
ALF had a final episode. He got captured by the Feds. No kidding, I've seen the episode.
No fanfilm as such, but if I won the lottery I would spend a small portion setting up a small independant film company specialising in oldschool film making techniques especially with regard to effects.
That would be my dream

Aliens 2
If I won that kind of coin, I'ld do multiple new seasons of Dead Like Me, Wonderfalls & Journeyman.
