Hmm. Since this is NEVER gonna happen I may as well go for broke!
I'd take that first million and hunt down the top five best models I'd ever seen as 'lees. I'd offer them up to 150,000 (yes, I said ONE HUNDRED FIFTY THOUSAND) apiece to do the video, which is probably far more than they were paid for everything they previously did combined. The condition would be that they'd each have to contractually agree to submit to the most intense and merciless tickling for at least a half-hour's worth of footage. I'd stipulate such knowing that some of that footage would have to be edited down to the best 20 minutes per model to make a nearly two-hour video.
Among my top 'lee choices would be:
1) Crystal from the old Realtickling video "Ticklish Merchandise"
2) Julia Parton
3) Jordan from the JPBFC clips
4) The model 'lee (name unknown) who played "Jay's" wife in episode #6 of the old California Star Tied & Tickled series from the 1980's.
5) Raven Knight from the FM Concepts line
If any of the above were unavailable or unwilling I'd have to find reasonable substitutes among the existing model population or else pay the others pro-rated additional fees for participating in longer segments!
I'd also spend another 50k to hire the Tickler in Black to participate as a 'ler. (He gets paid less since he'd probably be so happy to tickle all those highly responsive lees in succession he might very well do it for free! But since I HAVE to spend a million, he gets paid something.)
I'd create and direct all the scenes myself and I'd of course co-star as a SECOND TIB. We two guys would double team each 'lee in some very creative scenarios too elaborate to describe here. I'd rent a private space, or use the same ones Real Tickling used in their early tk vids, and I'd rent or buy top-notch sound and hi-def vid equipment to maximize the recording quality. I'd also have custom made gear to ensure the most restrictive - but not painful! - bondage for the scenarios I have in mind. Some would be pretty unique!
I'd feature each 'lee in her own twenty-minute tickle scenario, tailored just for her. The grand finale scene would be the TIB and me tickling the daylights out of all five 'lees non-stop for fifteen minutes!
Finally, I'd BUY the most sophisticated video editing gear I could find to edit and master the thing for dvd and online clip distribution. Oh and I'd also use my profit and share of sales proceeds to form my own independent TK vid specialty company with a very unique approach to the genre. How unique I'll just keep to myself since it isn't gonna happen anyway!
Well, that was certainly a fun fantasy...
And by the way, nobody would ever need to MAKE me sign a contract like that. I'd GLADLY do it just as I described.
