Quoted from J85M:
I was really disappointed when I read no dialogue/callouts from the films and Stern are using sound a likes but if they go the route laid out above by eskaybee I think it could be a lot better than audio from the film, BUT the rocket sound a like needs to be awesome!
That can't be right. It will probably have a mix of audio from the movies & sound alikes for custom pinball-related dialog...pretty much like every movie based pin Stern has done.
GB: movie clips + Ernie Hudson
SM: movie clips + J.K. Simmons
Avatar: movie clips + Stephen Lang
Iron Man: movie clips + sound-alike Jarvis & random military guy
BDK: movie clips + crappy "sound-alike" Batman, Joker, Scarecrow, etc.
ST: movie clips + sound-alike Klingon, Admiral Ritchie & Karl Urban
Tron: movie clips + David Theil's wife as the computer voice
The only movie Sterns I can think of that didn't have dialog clips from the movies were Pirates, but the game rules really didn't follow any movie narrative, so it worked fine with sound-alike Depp and the other pirates....and Avengers, which I think was an aesthetic choice after the complains about Transformers' shitty sound-alike not matching the movie clips...so they just went full on custom voices instead of movie clips.
Since GOTG is already showing they have rights to the movie footage, I can't imagine they wouldn't be able to use the corresponding audio to go with it.
