Believe it or not, the movie Demolition Man
(Sylvester Stallone, 1993) actually had a bit of paintball gear in it:
When Simon (Wesley Snipes) remembers he's in the future, and wonders
where all the "phaser guns" are, he wanders over to see this
"Soldier of the Future" holding a "magnetic accellerator" rifle. Note
the mannikin also has wristbands holding a dozen or so 12-gram
After Simon takes the "phaser gun"
(actually a mock-up of an H&K G11) he asks the computer how to
and a Sheridan P-68 SC
can briefly be seen in the background of the display, just above the phaser gun's telescope.
