Rapid Fire Theater rings in the holidays with a festive retelling of a classic Christmas film with an element of unscripted pandemonium.

The Theater Company’s Annual Holiday Special, Blank who stole Christmasit is mostly a musical script. The show consists of actors who have learned their lines, choreography and blocking – typical of any theater production.

However, since this is a Rapid Fire production, improv comedy will be thrown into the mix at some point.

Each night of the show, a guest improviser who will perform “The Blank” will join the rest of the cast and perform the rest of the show cold – as in, without rehearsing or knowing any of their lines.

The cast doesn’t even know who’s coming to play The Blank.

The special guest du’jour will get to choose his character and say whatever lines he can think of, while the rest of the cast will do their best to use him and somehow create a coherent story , but chaotic.

The holiday special features three versions of the show to cater to different audiences, starting with the family-friendly Nice show, followed by the Naughty 14+ show and the adult-only show, which has elements of foul language and questionable content – with certainly not for the easily offended.

In years past, guest improvisers have chosen to play characters like Barbie, Darth Vader and Whoopi Goldberg to eyebrow-raising characters like Scarface and Austin Powers.

The Blank Who Stole Christmas is a complete tribute to the Dr. Seuss book as well as the art of improv while providing laughs and entertainment for all ages.

Rapid Fire Theatre’s festive production will perform every Thursday through Saturday, November 28 through December 22, at the Rapid Fire Exchange at 10437-83 Ave.

Tickets are available online.
