Colin Farrell had no desire to imitate Arnold Schwarzenegger's Total Recall performance in the upcoming remake, insisting the film "felt different enough" from the 1990 original for him to make his mark on the role.

The Irish actor has taken over the part made famous by Schwarzenegger in the new adaptation of Philip K. Dick's story We Can Remember It for You Wholesale.

He appeared at Comic-Con in San Diego, California on Friday to discuss the Len Wiseman-directed film, and he is convinced movie fans will be impressed with the reboot.

Farrell says, "I didn't feel the need to fill those size 16 shoes or 18 shoes or whatever size foot Arnie has. The film felt different enough that I could go and make it my own. I did think about messing around with an Austrian accent for about seven minutes."

Wiseman's wife Kate Beckinsale also stars in the blockbuster, and the beauty admits she was surprised her husband cast her as a double-agent.

She joked to him during the panel chat, "I'm still offended that you thought of me for this psycho-b**ch role, but it's nice to be able to open up the crazy a little bit."

The film is set for release next month.
