Colin Farrell was "dubious" about appearing in a 'Total Recall' remake.
The 36-year-old actor - who plays the lead role of Douglas Quaid, originally played by Arnold Schwarzenegger, in the new film - admits he was nervous about taking on the role until director Len Wiseman showed him the differences.
He said: "I loved Arnie in the original 'Total Recall', which I was when I was 15 or 16. There were some funny one liners, there were some great action sequences and really fun performances from Arnie and Sharon Stone. So when I was approached about a new version I was dubious.
"But although the characters exist within the same story frame and are battling with the same conceptual elements, they're very different characters, and for me that was a relief."
Even Len wanted to avoid making comparisons to the first 1990 film, admitting he had "no interest" in simply remaking the movie with modern effects.
He added: "I had no interest in just remaking Paul Verhoeven's film with updated effects.
"And I didn't want to do another version of Arnold Schwarzenegger."
