Deadline Hollywood reports that Disney could be in the early planning stages for a big screen Phineas and Ferb feature.

Phineas and Ferb first premiered on the Disney Channel  on August 17th, 2007 and follows the antics of two gifted and creative brothers who look to keep themselves (and their friends) amused while on Summer vacation.  The series has done so well, in fact, that a made for tv feature titled Phineas and Ferb: Across the Second Dimension is also in the works and is rumored to air in August 2011.
