Writing comedy skits enabled him to hone his abilities with dialogue and narrative, and to explore the way comic timing is affected by the needs of a story: he was no longer simply throwing out one-liners.

At Warner Brothers, he worked not just on those titles, but also on Ozzy & Drix, Batman Beyond, and an adult animated streaming series based on the character Lobo.

He also produced a couple of public service announcements for the U.S. State Department (in a joint project with Warner Brothers Animation) that featured Bugs Bunny and Daffy Duck, in which Cambodian people were warned about the dangers of picking up stray ordnance from the ground.

A take-off on The Blair Witch Project, it was entitled The Glendale Ogre, and starred Marc Drotman, Scott Kreamer, and Kate Donahue.

Scored by Julie and Steve Bernstein, it featured camera work by David Coons of Los Angeles' Artscans, himself most well known as the inspiration for the title of Po Bronson's The Nudist on the Late Shift.

Since leaving Warner Brothers Animation, McCann has worked on Jimmy Neutron, Dave the Barbarian, Tom Ruegger's Sushi Pack, and Animalia.

McCann lives with his wife in the hills east of Los Angeles, and claims to like "long walks through large corporate and government buildings."
