The Dallas Theater Center’s summer musical is, as usual, a family friendly show, and this time, it’s Joseph and the Amazing Technicolor Dreamcoat. It doesn’t open until June 22, but you can get a preview of DTC’s version, followed by a screening, tomorrow evening. For the second year, DTC has paired up with Studio Movie Grill on 75 and Royal for a meet-and-greet Q&A session, where you can visit with the cast of DTC’s production (including recent B’way veteran Liz Mikel, pictured) and then watch the filmed version of the show, starring Donny Osmond, in a sing-along. And all of it is free. Doors open at 6:45 p.m. on June 5 to meet the players, with seating at 7:10, Q&A at 7:30 and the movie at 7:45.
