In "Total Recall," Farrell plays a factory worker who is suddenly a wanted man but he has no idea why. The film, in part, involves turning dreams into real memories.
So what's real? What's not? And why do people want Farrell's character dead? He says this "Total Recall" doesn't have quite the same vibe as the Schwarzenegger version.
"It felt different enough that I didn't feel that I was stepping into Arnie's shoes, because God knows, the man casts a big shadow and little old me would have failed miserably," Farrell said.
Kate Beckinsale plays one tough woman in the movie, which was directed by her husband, Len Wiseman.
Where does that feistiness come from?
"I don't know, I guess my husband must have spotted it at home," she said with a laugh.
Beckinsale is not the only tough woman in the film. Jessica Biel is also a force who's not afraid to fight.
Biel said her fiancée, Justin Timberlake, has not seen it yet, so she thinks he's in for quite a surprise.
"Total Recall" opens Friday.
