as: Douglas Quaid
First off, let me point out that, while there have been two movie versions of Total Recall, we’re putting Tom Wopat in the 2012 film because the original, 1990 version is just too weird and too ‘90s to mess with—it truly is perfect in its imperfection. Besides, there’s a limit to how many times can we insert Wopat into Schwarzenegger movies.
Instead, we’re putting our beloved Tom Wopat into the lead role in the remake/reimagining of the film, taking the place of Colin Farrell, who should under no circumstances be the leading man in a would-be blockbuster movie of any type. This version is also more of a straightforward sci-fi action flick, and less of a campy, bizarro, sci-fi mindbender. That, too, makes it better suited to Wopatization.
The biggest change in a Wopat-for-Farrell swap is the age difference: Wopat is 25 years older than Farrell. However, this could actually work just fine, with minimal other alterations. Instead of being a production floor working stiff at the precision metal stamping company that makes parts for the police robots seen in the movie, the Quaid character could be the manager of the plant, having climbed the ladder from factory worker to head honcho.
This change could make the rest of the film a bit more potent, in fact. As Quaid eventually discovers, he is actually a secret agent* who has been given new memories by former employers. Instead of just a few months of living this lie of a life, he would’ve been at it for decades. When he finally uncovers the truth, he would be even more torn between the “new” life he’s been living and his true identity.
One other potential concern regarding having a considerably older actor in the role: the ladies. Normal, real life people are usually married to someone roughly their same age (though there are certainly exceptions). But, in Hollywood movies, older dudes end up “married” to much younger women all the time. Would the parts of Quaid’s “wife” and secret-agent ladyfriend still have been played by Kate Beckinsale and Jessica Biel, respectively? Quite possibly, because, Hollywood is stupid that way.
As for the action sequences, not a lot would need to change. Still spry and athletic in his mid 60s, Wopat could easily hold his own in fight scenes and chases across the late-21st century landscape.
