The video says it all, folks.
Here, the stage ops crew changes out the set for OSF's 2013 production of "The Liquid Plain" for our "Unfortunates" set.
This is in our Thomas Theatre, an intimate 270-360 seat thrust stage.
That is a 10 x 10 FOOT lift center stage that is also in rep. It later becomes a broken shape trap.
All of the softgoods are changed out and a huge faux plaster beam just stage left of center is put in.
They do this in under two hours.
