Indiana Jones - lots of potential here
Robotech - So many characters, and great vehicles. Matchbox didn't do it justice
Predator - The movie. Just the Predator alone isn't enough, how about the Special Forces team with Dutch and Blaine?
Starship Troopers - Mobile Infantry against bugs anyone?
Holy crap! I posted this 9 years ago?
We got a bunch of Indiana Jones, so that's cool.
McFarlane has done some cool Predator stuff.
Toynami has done some cool Robotech stuff, including their masterpiece edition Veritechs.
As for Starship Troopers? Eh. Poor choice on my part in retrospect.
As for now?
GAME OF THRONES - Definitely lots of potential here for core characters and some army building. I'd love to get some Stark forces, Lannister soldiers, Dothraki, Nights Watch and Wights. But seeing how the show is so far removed from being oriented towards kids, this line would probably have to remain a dream.
HIGHLANDER - The first movie could probably yield about a dozen or so figures. It would probably be best served by a company like McFarlane or NECA.
