His manager, Brett Carducci, is also producing.
Lionsgate bought the spec script from Andy Selsor Tuesday. "The Chung Factor" is his first sale.
The movie is about a nice guy who meets the girl of his dreams after being unlucky in love. But because he's afraid of screwing up the relationship, he takes advice from an offbeat relationship coach, played by Jeong.
As it turns out, the coach is actually the woman's ex-boyfriend and is out to sabotage the relationship and win her back.
The script, formerly called "The Ex-Factor," was on the 2005 Black List of best unproduced scripts.
Jeong is repped by UTA and Carducci at Aligned Entertainment.
Selsor is repped by Original Artists.
