The eighth annual madcap 50-Hour Improvathon is returning, this time with a homage to all things Hollywood. A group of 25 actors play the whole 50 hours, without going to sleep, while guest performers pop in to liven things up. There are some good cast members too - including Mike McShane and Ruth Bratt. It starts at 7pm on Friday 29 May and ends Sunday 31 May at 9pm. Good luck trying to stay the course.
