Mason does not appear to have got a part in the movie Holes as 15-
year-old actor Shia La Beouf has signed on for the lead role of
Stanley Yelnats. Shia's had guest appearances on several TV shows
(including ER), been in a few TV movies, and had his own TV show on
the Disney Channel for a while called Even Stevens.

I will continue to check if Mason auditioned for this movie but have
come up with a blank so far.
