It seems Albert Einstein wrote a Theory of Everything and secretly left it with his assistants — who are now getting killed off. A history prof and his physicist ex must find it, as terrorists and the feds give chase in Mark Alpert’s Final Theory.

Movie Pitch
Da Einstein Code.

Bottom Line
A preposterous plot, but Alpert offers a smoothly propulsive airplane read — until some midflight turbulence and a very bumpy crash landing. C+
