Ben Stiller and Reese Witherspoon revive sci-fi clone romance Ben Stiller and Jim Carrey’s long shelved sci-fi comedy Used Guys is being revived with Stiller and Reese Witherspoon as the lead characters. The initial project centred on cloned men who were traded by women. Stiller and Carrey were to play obsolete models who go in search of ‘Mantopia’, but the film was cancelled as the budget spiralled past $100 million. Now however it seems Fox is moving forward with the film again, changing the story to focus on the relationship between Stiller’s character and Witherspoon’s clone owner. Jonathan Dayton and Valerie Faris (Little Miss Sunshine) are in talks to direct with a script from Dave Guion, Michael Handelman and Mickey Birnbaum.
