First, I'd settle the dispute between Warner Bros. and Turner Broadcasting and get the Looney Tunes back on TV. Then I'd swing by Disney and finish up the DVD releases of their animated shows - the final volumes of "Gargoyles", "Chip 'N Dale", etc. along with sets for "Goof Troop", "Bonkers", and so on (and yes, that includes "Kim Possible"). Then I'd hit Viacom and do the same thing for the Nicktoons.
Now for the pipe dreams. I'd fund all those ideas I have for 2-D animated movies - both my original concepts (Maxine, '94, etc.) and pre-existing properties (FoxTrot, Bloom County, and so on), in my attempt to usher in another 2-D boom. Then I'd go to 20th Century Fox and get my "Meg" spin-off put into production, making sure Seth MacFarlane doesn't come anywhere near it. Then I'd go to Viz or PUSA or whoever is in charge of this sort of thing and finance uncut Japanese subtitled DVD sets of "Pok?mon". Oh, and I'd go back to Warner Bros. and finance my Looney Tunes-based Watchmen parody for a direct-to-DVD release.
In the words of Homer Simpson, "I could do a lot of things if I had some money..."
