In this, the Reality Age, it's surprising that there isn't an ongoing reality competition on TV about making theater. But once again, real life steps up when TV lets you down. Theatre Lab and Players Project Theater Company have joined forces to present 24-Hour Play Festival. Last week seven playwrights randomly selected cast sizes, genres and settings for a new play. Each of the seven then had one week to write a play using those elements. Then seven directors pulled those scripts from a hat (it's a big hat) and had just 24 hours to rehearse their play with a cast. Tonight at 8 p.m. at Webster Groves High School (100 Selma Avenue, Webster Groves; 24hourplayfest4.brownpapertickets.com), those seven new plays are performed for the first time. The show is a fundraiser for Theatre Lab's next production, but it's also an opportunity to see local actors and actresses work in a more off-the-cuff show than is typical. But don't worry about mistakes — these folks are pros. Tickets are $15.
