Fox has found the mad scientist for its Frankenstein pilot.

Deadline reports that Adhir Kalyan, best known for his four-year stint as Timmy Patel on the CBS sitcom Rules of Engagement, has signed on to play Otto Goodwin. Along with his bio-engineer twin sister Mary, billionaire Otto helps bring FBI agent Ray Pritchard back to life as a younger, stronger version of himself.

This take on Mary Shelley's classic novel was announced in October. Rand Ravich, who created Life and Crisis, wrote the pilot and will serve as an executive producer alongside Howard Gordon (24, Homeland).

Mary Goodwin and Ray Pritchard haven't been cast.
