Great Job Growing Up, Jake Gyllenhaal

Jake Gyllenhaal appeared on Good Morning America today to promote Source Code, but GMA had other plans.  A red-faced Gyllenhaal was caught off-guard when a clip from his very first movie, City Slickers popped up on the monitors.  The then ten-year-old future stud starred alongside Billy Crystal in the 1991 comedy with a buzz cut and contorted faces.

Gyllenhaal joined co-star Michelle Monaghan at a private screening of Source Code last night in New York City.  Also in attendance at the Crosby Street Hotel were Lindsay Lohan, Jesse Tyler Ferguson, Duncan Jones, Jeffrey Wright, Frederique van der Wal, Kevin Zegers, Tyson Ballou, and Rufus Wainwright.
