Pic still stars Charlie Hunnam and Jessica Chastain
Cumberbatch left in the middle of August and Legendary worked fast to find his replacement. Hiddleston joins Charlie Hunnam, Jessica Chastain and Mia Wasikowska in the pic.
Plot details are unknown as del Toro and Lucinda Coxon work through a rewrite on a script del Toro and Matthew Robbins originally penned.
Legendary will produce and be a participating financing partner on the movie, with Universal Pictures retaining an option to finance at a later date. The film is set to begin shooting in February 2014.
The WME repped Hiddleston can be seen next in “Thor: The Dark World.”
