The Clown Prince of Crime
Super Freak
Sounds like there will be more than what they've shown here and I hope they aren't just talking about the cartoon figures. You've gotta at least have Doc. If the line seems to bomb with both Marty and Doc available I could maybe accept them not wanting to continue - but Marty alone as a testing ground would not be giving it a reasonable chance IMO.
I think Doc in the white costume is a given. I don't see that many charcters from that film being very toyetic. Is BTTF THAT popular? Most of the cast are people in street clothes. George McFly that popular?
BTTF2 is better suited for figures than part 1 because of the costumes, imo. Beef and Marty with their hover boards could be good figures, along with Doc in yellow. The Western look too, although I have no interest in BTTF3.
The car was always the key item and star of the franchise when it came to merchandise. Don't get me wrong, an ultimate Marty and Doc are cool, and I will get them, but I just don't see BTTF as an obvious franchise to make a large line of figures. Hell, not even the Rocky line which has like 8 movies and tons of costumes and villains could make it far because of low sales.
