MASS EFFECT
Q: Will it just be an adaptation of the first game, second game, or a completely new story?
A: It will be a completely new story
Eh, okay. Better than messing up the games, I suppose...
Q: How are you going to address the element of 'choice' that the players have in the game?
A: A movie narrative is different than gameplay. There won't be a choice aspect to this film, just a normal film narrative.
Just as well. It'd be weird for the audience to stop the movie and take a vote.
Q: Will it be a trilogy?
A: We are really focused on making this a great movie, so we'll see where it takes us. We have to get the first one right to know whether there will be more.
Good, good. Don't push sequels.
Q: Will Seth Green portray Joker (that character he voiced in the game?)
A: No.
OUTRAGE.
Q: Will the movie be focused on Sheppard?
A: Yes.
But... but my headcanon!
Q: If the movie is focused on Sheppard, will it be the male Sheppard or the female Sheppard?
A: Male.
BUZZKILL.
Q: Can you give any hints to potential casting?
A: No. Stay tuned.
Good, because I am already disappointed.
Q: Will BioWare allow plot / character changes?
A: Yes, we are working closely with BioWare on the development of this project.
Based on other supplimental media they've supervised, I have little faith that this will improve the quality of the overall work. But I suppose it wouldn't hur--WHAT DO YOU MEAN PLOT/CHARACTER CHANGES?!
Q: Would you consider Daft Punk to do the soundtrack?
A: We love Daft Punk, but it's too early to say who will produce the soundtrack.
OH FFS WHO EVEN ASKED THIS QUESTION. Let's not force Daft Punk to do movie soundtracks, mmkay?
Overall summary: NOOOO, NOT THE CANON! NOT ANOTHER HORRIBLE GAME MOVIE!
