Back in September 2011, my first fan cast was for a Mass Effect film. Somehow, I never made a sequel to it despite great feedback in the comments section.
Mass Effect Cast:
Commander Shepard: Michael Fassbender*
Dr. Liara T'Soni: Summer Glau
Kaidan Alenko: Zachary Levi
Saren: Andy Serkis/Fred Tatasciore
Ashley Williams: Olivia Wilde
Tali'Zorah nar Rayya (vas Normanday): Alison Brie*
Garrus Vakarian: Bryan Cranston*
Urdnot Wrex: Ron Perlman
Jeff "Joker" Moreau: Seth Green*
Captain David Anderson: Laurence Fishburne
Donnel Udina: John Slattery
Matriarch Benezia: Kate Winslet
*Appears in Mass Effect 2
Illusive Man: Martin Sheen
Miranda Lawson: Yvonne Strahovski
Jacob Taylor: Anthony Mackie
Jack: Olga Kurylenko
Thane Krios: Viggo Mortensen
Mordin Solus: David Tennant
Due to the large size of the cast in Mass Effect 2, I decided to remove some of them because it would be impossible to give character development to each of them.
