"Lord Of The Rings" Star Turning Strange?

Filming for the 2013 sequel to "THOR" is underway in the UK (set pics on there way) and new rumours have already started. The big main rumour is that Doctor Strange is set to make a brief appearance to set him up for his own film in Marvel's MCU: Phase 3, but he may be included in "The Avengers 2" before his own film.
Casting rumours have started up again on who will portray Strange on the BIG-screen. Actor Joel Edgerton was strongly rumoured to be taking on the role, but now it seems that Aragorn himself, Viggo Mortensen is reportedly in negotiations with Marvel to play a key role in a MCU: Phase 2 film. Fans and online sites are all assuming that it's Doctor Strange after seeing this tweet by some dude on Twitter called Roger Wardell. 

"Inside News: Marvel is in negotiations with Viggo Mortensen for an unspecified role in in one of their Phase 2 films."

"Inside News: There's something "Strange" about Thor: The Dark World."

I guess it would be interesting to see Mortensen as Doctor Strange, but he is a bit too old for the role. I've always thought that the studio would go for a younger actor, but he is an amazing actor, so it could work well. Hopefully this rumour is true then people!!!
