When last we talked about NBC's cult comedy series, Community, we were at Comic-Con, rejoicing that the entire cast would be returning, but lamenting the absence of creator and show-runner, Dan Harmon.  While we wait to see if new overseers David Guarascio and Moses Port can keep the old Community magic, season four will see an infusion of overseas humor with the addition of British comedian, Matt Lucas (Bridesmaids). Lucas, perhaps best known for British comedy series Little Britain, will star as Greendale Community College's newest faculty member.  Hit the jump for more details on his character as well as a look at a great fan-made Inspector Spacetime poster.TV Line reported on Lucas' addition to Community's cast as a history professor who will appear over multiple episodes.  His character, who previously taught at Oxford, possesses a strict academic rigor that does not quite jive with the laid back, inept learning environment of Greendale. Like most characters on Community, the professor's polished exterior hides an emotional mess beneath the surface.In other Community news, former showrunner Harmon shared this fan-made poster for internal TV show, Inspector Spacetime on his personal blog (via io9).  A favorite past-time of Troy and Abed, the show is a thinly veiled reference to Doctor Who (much like Untitled Web Series About a Space Traveler Who Can Also Travel Through Time is a thinly veiled reference to both shows). Check it out below:inspector-spacetime-fan-posterThe whole gang, including Joel McHale, Danny Pudi, Donald Glover, Chevy Chase, Yvette Nicole Brown, Alison Brie, Gillian Jacobs, Jim Rash and Ken Jeong will resume classes this fall. Look for Community to debut its fourth season, now on NBC's Friday nights, starting October 19th.community-nbc-cast-poster-image
