Days after Theresa Peters left the William Morris Agency, United Talent Agency has hired her as a partner and agent in its talent department.

She signed late Friday and Saturday, UTA issued a release declaring that Peters would bring her client list, including James McAvoy, Kirsten Dunst, Jeffrey Dean Morgan, Rachel Bilson, Mandy Moore, Hugh Dancy, Joshua Jackson, Justin Chatwin, Eric Christian Olsen, Brian Geraghty, Joseph Cross, Jason Clarke, Rachael Taylor, Isabel Lucas, Emma Booth and Emily Browning.

WMA countered Sunday that Taylor, Booth, Bilson, Lucas, Clarke and Olsen haven’t left and are expected to stay at WMA.

UTA said it has confirmed that Olsen, Taylor, Lucas and Booth are indeed coming to be repped by Peters, leaving Bilson and Clarke as the only uncertainties.

Regardless of the final tally, Peters bolsters a UTA talent roster that has been gaining momentum following the exits of three partners to Endeavor six months ago with such clients as Ben Stiller and Jack Black.

UTA adds McAvoy — expected to topline a “Wanted” sequel being developed by Universal and Timur Bekmambetov — and “Spider-Man’s” Dunst to such recent talent additions as Gwyneth Paltrow, Jennifer Lopez and Miley Cyrus. UTA also recently hired manager Doug Johnson to be an agent in its lit department.

Peters, who becomes the 18th partner at UTA, had been with WMA for 14 years.

In a statement, UTA’s board of directed cited Peters’ track record and the fact that she is “respected by both the talent and executive communities for her taste in material, eye for emerging talent and ability to build successful careers.”
