The series showcased the improvisational skills of a group of four actors each week, as they walked into a live sketch without having seen a script for it. The only clue the actors had as to the content of the sketch and the role they would be playing within the sketch, was their costume.
Upon entering the sketch, the actors were greeted with "Thank God You're Here!" from another actor in the sketch. Outside of the principal actor, all actors in the sketch had a script which they more or less followed, depending on the improvisations. Sketches had no set ending point; instead, they went on until the judge (Foley) stopped them with a buzzer. Also, in each episode one of the skits would feature David Alan Grier in a surprise cameo.
At the end of the show, the judge chose a winner from among the four actor contestants. The winner, was awarded a trophy. Unlike the Australian version, no honorable or dishonorable mentions were chosen.
The following countries that have previously aired their versions of Thank God You're Here includes:
- Australia (country that originated the program)
- Czech Republic
- United Kingdom
