There are reports that Josh Brolin, star of Oldboy and Sin City has been cast as the voice of Thanos in the upcoming Guardians of the Galaxy film.
Now whilst this is still rumour until Marvel confirm it shows that Marvel aren’t stumping on casting awesome actors for voice only work. Much like James Spader in Avengers 2 and Vin Diesel / Bradly Cooper in Guardians.
Nothing has been said about Brolin maybe doing the capture work as well giving Thanos both his swagger and voice but thats neither here nor there at the mo.
Here is the report from comicvine.com:
Ever since Thanos made a cameo in The Avengers, many of us have wondered when the cosmic powerhouse will show his purple face again. There’s been a fair amount of talk about which actor will step into the Avatar of Death’s giant boots, and, according to Variety and Latino Review, W. and Oldboy star Josh Brolin will be transformed into the evil character. Latino Review claims Brolin will serve as the voice of Thanos in Guardians of the Galaxy.
