EXCLUSIVE: Will Kemp (Step Up 2) and Kellee Stewart (the Hot Tub Time Machine franchise) are set to co-star opposite Alicia Silverstone in the Lifetime drama pilot HR. Written by Glenn Porter, HR centers on the uptight Director of Human Resources for a global company Ellen (Silverstone) who, after a head injury alters her outlook on life, throws standard corporate practices out the window and inspires the business to strive for new ambitions and profits. British actor Kemp, repped by Gersh and Wishlab, will play Piers Moore, a British salesman, co-worker and potential love interest for Ellen. Stewart, repped by Domain and manager Robyn Bluestone, will play Judith, a coworker of Ellen in the HR department. Aaron Kaplan of Kapital Entertainment is exec producing.
