Caroline Rivera is Norma Desmond in the Greater Lewisville Community Theatre’s 30th anniversary season opener in the regional premiere of Sunset Boulevard, the musical by composer Andrew Lloyd Webber and librettists Christopher Hampton and Don Black. The production opens this weekend and runs through Nov. 4, with performances at 8 p.m. Fridays and Saturdays and 3 p.m. Sundays. An additional 8 p.m. performance has been added on Thursday, Oct. 25. In the musical, silent movie star Norma Desmond longs for a return to the big screen, having been discarded by Tinseltown with the advent of “talkies.” The theater is located at 160 W. Main St. in Old Town Lewisville. Tickets cost $19 for adults, and $16 for ages 65 and older and those younger than 18. For reservations, call 972-221-7469. For more information, visit www.glct.org .
