Mullinger burst onto the UK comedy scene in 2005 when he reached the finals of Jimmy Carr’s Comedy Idol, after just six months performing stand up. His performance in the final alongside Carr at The Comedy Store was filmed for Carr’s bestselling live DVD. In the subsequent 18 months he reached the finals of two other national new act competitions, appeared on a UK TV panel show and set up his own comedy club working with comedians such as Stephen Merchant, Michael McIntyre, Stewart Lee, Darrin Rose, Russell Brand and Sugar Sammy. He has also appeared on stage with Russell Peters at London’s 3,600 seater Hammersmith Apollo.
In 2012, Mullinger hosted the world’s first funny film review show ‘Movie Kingdom’ on TV channel DMAX which saw him riffing with Judd Apatow, Simon Pegg, Robin Williams and his all time hero Jerry Seinfeld. He also conducted hilarious interviews with A-list Hollywood stars such as Daniel Craig, Channing Tatum, Matthew McConaughey, George Clooney, Tom Cruise, Robert Downey Jr, Cameron Diaz and many more. The aim was always to make them laugh and he rarely failed. But when he did (most famously with a miserable Anne Hathaway), it was even funnier! This led to a web series for Comedy Central which saw him appearing with Seinfeld again as well as Amy Schumer, Lewis Black, Jim Jefferies and Gina Yashere.
