Pair joins 'Invisible Sign'

J.K. Simmons, Chris Messina cast in indie fable

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.
