J.K. Simmons and Chris Messina (“Vicky Cristina Barcelona”) are joining Jessica Alba in the whimsical fable “An Invisible Sign of My Own.”

Marilyn Agrelo’s “Amelie”-style indie follows the transformation of a sheltered, math-obsessed teacher when a new science teacher arrives at her school.

Jana Edelbaum, Lynette Howell and screenwriters Pam Falk and Mike Ellis are producing the iDeal Partners Film/Silverwood Films production.

The Endeavor/Authentic-repped Messina will next play Amy Adams’ husband in “Julie & Julia.” The Gersh-repped Simmons recently followed up “Juno” with “Burn After Reading.”

Kimmel International will rep foreign sales at next week’s American Film Market, with Endeavor Independent repping domestic.
