After the John Hutchings Museum of Natural History moved to the Memorial Building in 1996, the former museum was renovated and reopened as the Lehi City Arts Center. Limited by its 100-seat auditorium with a combined green and dressing room, the Lehi Arts Council announced plans in 1998 for a new performing arts complex with a 1,800 seat Broadway theater, a smaller 248-seat theater, and a theater-in-the-round. Pledges were secured for $6 million of the necessary $15 million, but fund-raising grew difficult due to competition from other Utah County arts initiatives and the 2002 Winter Olympics Games. In 2003, Lehi City unveiled a $150,000 renovation of the existing arts center.
The Rex Theatre in Castle Dale closed about 1930. The Ferron ward of the Church of Jesus Christ of Latter-Day Saints acquired the projection equipment of the Rex Theatre in 1930 and began showing movies in the local meetinghouse.
