While we’re excited about Christopher Guest’s return to filmmaking with the HBO series “Family Tree” this week, his first original comedy since 2006’s awards season send-up “For Your Consideration,” we’re equally enthused about the Stateside arrival of Nina Conti, the British ventriloquist who will be bringing along her foul-mouthed monkey Monk with her to steal scenes as one of the eccentric relatives of a man (Chris O’Dowd) who hits the road with genealogy as his guide.

Though Conti made a brief appearance in “For Your Consideration” as a TV anchor, it seemed as though it was only a matter of time before she became a featured player in one of Guest’s productions after the “Waiting for Guffman” writer/director lent his name as an executive producer to her surreal 2012 documentary “Her Master’s Voice,” which follows the comedienne as she pays tribute to a former mentor. We adored the film when it premiered at SXSW – our review is here – and since it’s now available to watch online via Hulu, you might want to catch up on the unique performer before her big debut on Sunday night.
