(from Disney XD's press release, January 2015) "Penn Zero: Part-Time Hero," an animated comedy adventure series about Penn Zero, a regular boy who inherits the not-so-regular job of part-time hero, is set for a simulcast premiere FRIDAY, FEBRUARY 13 (9:45 p.m., ET/PT) on Disney XD and Disney Channel, with three additional episodes premiering over the holiday weekend on Disney XD. The notable guest cast for season one includes Garry Marshall ("Happy Days"), Beau Bridges ("The Descendants"), Sigourney Weaver ("Avatar"), Sean Astin ("Lord of the Rings"), Wanda Sykes ("The New Adventures of Old Christine"), Jason Alexander ("Seinfeld"), Jeff Gordon (NASCAR driver), Diana Rigg ("Game of Thrones"), Paul Reubens ("Pee-Wee's Playhouse"), Jane Kaczmarek ("Malcolm in the Middle"), Elizabeth Henstridge (ABC's "Agents of S.H.I.E.L.D."), Adam West ("Batman"), Chris Parnell ("Saturday Night Live"), Peter Stormare ("The Blacklist"), Maria Bamford ("Arrested Development") and Olivia Holt (Disney Channel's "I Didn't Do It"). "Penn Zero: Part-Time Hero" follows Penn Zero and his best friends Sashi, an overqualified part-time sidekick, and Boone, an under-qualified part-time wise man, as they zap to other dimensions to fill in for heroes in need. Each mission takes the team to unpredictable epic worlds where they must battle evil part-time villain Rippen and his part-time minion, Larry. Whether superhero, fish-prince, clown cop, giant monster or tiny action-figure, Penn uses his unconventional heroic skills to save the day - his own way.
