Colin Farrell Starring In Total Recall?

HeatVision reports that Len Wiseman's (Underworld, Die Hard 4) Total Recall reboot could get it's new Douglas. They say that Colin Farrell is the front-runner for the role previously portrayed by Arnold Schwarzenegger. Tom Hardy (Max Mad 4, Batman 3, Inception) and Michael Fassbender (300, Inglourious Basterds, X-Men: Fist Class) have also been in talks for the role. This wouldn't be Farrell's first jump into the world of Philip K. Dick he had a small role in Minority Report which was based on Dick's work. I'm just curious if they'll water this version down to PG-13 since they've already mentioned not going to Mars. I hope there is still science fiction involved because if there is lack of action like the extreme violence of the original film I'm not sure people will like this. The Adjustment Bureau another Dick adaptation looks like it's beyond generic so I'm nervous to support this remake. The worst thing they could do is make this a by the numbers PG-13 action film without heavy science fiction elements like Mars.
