CAA has added Tony nominee Enda Walsh and scribe-musician Ethan Lipton to its roster of stage talent.

Brit writer Walsh penned the book for “Once,” which scored 11 Tony noms including one for Walsh’s book. He also recently helmed a well-reviewed production of his own play “Misterman,” which had a run toplined by Cillian Murphy at Gotham’s St. Ann’s Warehouse last year.

Walsh has written plays including “Penelope,” “New Electric Ballroom” and “The Walworth Farce,” as well as the screenplay for Steve McQueen’s 2008 pic “Hunger.” In the U.K. he’ll continue to be repped by Nick Marston at Curtis Brown.

Ethan Lipton attracted attention earlier this year with “No Place to Go.” A hybrid play-with-songs in which he also starred, the world preem at the Public Theater’s Joe’s Pub picked up an Obie. His play “Luther” is set to be seen this summer in a production by Clubbed Thumb, while “Red-Handed Otter” gets a stint at the Cherry Lane Theater in the fall.
