United Talent Agency has signed Nick Frost, the British multi-hyphenate who co-stars in and co-wrote Paul, the Universal sci-fi comedy that opened today.  He joins co-writer Simon Pegg, who is already in the UTA fold. Frost, who had been repped by CAA, co-starred in Shaun of the Dead and Hot Fuzz, and is also known for the UK series Spaced and Man Stroke Woman. Frost also starred in the Joe Cornish-directed Attack the Block, seen at South By Southwest, and Paramount’s upcoming Steven Spielberg-directed The Adventures of Tintin: The Secret of the Unicorn. Frost will continue to be managed by the Safran Company and UK-based Hamilton Hodell.
