He also acted in 3 Ninjas: High Noon at Mega Mountain, P.U.N.K.S., Race to Space, and Grindhouse.

[citation needed] He got the role of Crash Bandicoot after Joe Pearson suggested that he call Jason Rubin (who was looking for a voice artist).

The recordings that O'Brien did for Crash Bandicoot were done in an intimate setting at the Alfred Hitchcock Theater.

[2] O'Brien also performed additional voices for the animated series adaptation of Spawn and Ralph Bakshi's Spicy City.

[citation needed] He was also in talks to have a role in Antonblast, a video game partly inspired by Crash Bandicoot; however, O'Brien died before this could occur.
