Splinter Cell, of course, is the classic stealth game franchise from Tom Clancy and Ubisoft. Players have been assassinating and sneaking around as Sam Fisher for years and seeing the property adapted into a film would be pretty exciting, particularly if UbiWorkshop is involved, as they are not willing to sacrifice on the series' integrity just to make a dollar.
According to rumor, Paramount is most likely to end up producing a Splinter Cell film, and they have had experience adapting other Tom Clancy works in the past. It is unclear, since Splinter Cell is made up of both novels and games, whether Ubisoft would be directly involved in this project.
As for Watch Dogs...
Fusible is reporting that Ubisoft has registered domains for Watch Dogs, including: http://watch-dogsmovie.com/, http://watch-dogsthemovie.com/ and http://watchdogsmovie.com/. Watch Dogs was one of the most exciting games we saw in Los Angeles at E3 earlier this month, so we're interested to see if Ubisoft is protecting their property or if there are actually plans in motion to produce a film based on the exciting game.
Watch Dogs and Splinter Cell: Blacklist are both due to release in 2013, so there is plenty of time to learn more about these potential films. Stay tuned!
