J.K. Simmons and Chris Messina have signed on to join Jessica Alba in Marilyn Agrelo’s upcoming drama “An Invisible Sign of My Own.”

Based on the novel by Aimee Bender, the film follows a reclusive math teacher (Alba) whose life takes a turn when a new science teacher starts working at her school.

Details about Messina’s and Simmons’ roles are unknown at this point. Variety describes the project as an "Amelie"-style indie.

Simmons can currently be seen onscreen in “Burn After Reading.” His future projects include “Jennifer’s Body” and “Crazy on the outside.”

As for Messina, he most recently starred in Woody Allen’s “Vicky Cristina Barcelona” and “Humboldt County.” He’ll also appear in Nora Ephron’s “Julie & Julia.”

Final word: Sounds like an interesting project, although I’m not quite sure about this “Amelie”-style thing. “Amelie” is a unique masterpiece no one can get remotely close to.
