As Peter Hall reported last month, Franco is playing the young scientist who is trying to discover a cure for Alzheimer's, and is part of a team who experiment on apes. One ape evolves, and Franco becomes attached to him, and takes him home to prevent him from further exploitation. Lithgow will play Franco's father, who has been stricken with Alzheimer's Disease. You and I both know Lithgow will knock this out of the park, so his addition alone is probably worth the price of admission.
Pinto will be playing the female lead, "a primatologist." Presumably she'll also be a love interest for Franco. Someone is bound to make remarks that primatologists aren't as lovely as Pinto, and all I have to say to that is Jane Goodall. Journalists complained she should have been a fashion model. So there you go.
Apes begins shooting this summer. It may be a "reboot", but like Logan's Run, it has some potential. I think it's going to be one of the more promising things on pop culture's radar.
