Sean Astin Gets Colorful!

Sean Astin ran the Color Me Rad 5K in Birmingham AL, where he is currently filming the family comedy "Mom's Night Out." For those not familiar with color runs, participants get doused with dyed cornstarch. Why? Beats me, but it's fun! Plus lots of photos ensued!

A proud and colorful Sean following the race!

Sean organized runners to form a "3" for the #Run3rd Photo Challenge.

It must have been fun cleaning up the inside of the car later!
