The movie
Rampage (Uwe Boll, 2009) features a couple bits of paintball gear.

Through the first half of the movie, Bill Williamson (Brendan Fletcher) constructs a suit of bulletproof armor, capping it off
with a set of V-Force ProVantage paintball goggles. (Which, it should be noted, are not in the least bit bullet resistant.)

After Bill's rampage, he calls up a friend (possibly also named "Bill", uncredited) who is waiting out in the woods for a little
one-on-one paintball, with a Tippmann X7 Phenom and what's probably a set of Empire Invert Helix goggles.

While
he waits, he randomly pops off a few shots at the trees- apparently
with actual paint, although the marker is never seen actually being
used.
