SCI FI Wire talked to Zack and Deborah Snyder, the husband-and-wife directing/producing team of Watchmen, who said that the film’s final length hasn’t been approved yet, but that it is getting shorter:
“We’re getting really close,” producer Deborah Snyder said in a telephone interview on Nov. 18. “We’re at two hours and 35 minutes.”
Director Zack Snyder added: “The movie’s pretty long … compared to 300, which was an hour and 58 minutes. The director’s cut [of Watchmen] is about three hours and 10 minutes long. It has even more than the theatrical version as far as the detail that gets even closer to the graphic novel.”
There’s also the “Tales of the Black Freighter” version in the works which you can read much more about here!
