'The movie - which is still something that's out there'

If they were to do something live-action in the Mass Effect universe, I'd rather see it made into some kind of series like the Expanse. Safe options would be to focus it on either the early days of the Systems Alliance, the First Contact War or something set in Andromeda.

If they did do something set during ME1, it would have to be a "Meanwhile..." sidequel where we're following a totally different Alliance ship and crew dealing with their own unique plotline. Shepard's gender and background could be left vague, but we could still have moments where we bump against the game.

We could see a bunch of Alliance soldiers go to Chora's Den for a drink, only to find dead bodies everywhere from Shepard's fight with Fist? Or be sent to deal with the aftermath of another Rachni, Geth, Husk experiment by Cerberus? And seeing the battle of the Citadel and Sovereign from another perspective would be incredible.

Would be an especially nice addition if they could have Yvonne Strahovski show up as Miranda, either as a minor character or merely a brief cameo. Would tie it closer to the games and give us a look at what she was doing during the events of the first game.
