As of season 4, a theatre finale is recorded two weeks before it's due to air. To keep the winner secret, the top queens are each filmed winning and they find out at the same time as everyone else who has won.
In Season 8's Snatch Game, guest celebrities Gigi Hadid and Chanel Iman gave such poor answers to Ru's questions that he angrily stormed off set at one point to scold the producers for not preparing them better.
Season 5 was the last season to give queens immunity due to Alyssa Edwards' Katy Perry impersonation in Snatch Game being so bad.
Immunity returned, in a new format, for Season 16.
In the first season, The Workroom and Runway sets were both located in the basement of the current World Of Wonder studio on Hollywood Boulevard. As of the second season, the show has used a larger runway and workroom on sound stages, above ground.
Each season takes roughly four weeks to film from start to the penultimate episode.
