Downright Upright is an improv blog by LA-based improviser, Sean London. Its focus is unabashedly UCB-centric, and that’s cool, because it’s fun to get an insider’s perspective on that scene.

London posts an interesting mix of personal “ramblings,” interviews and opinions, as well as great video content. I especially liked his review of a solo Jason Mantzoukas show. Already something of a legend in the States, Mantzoukas is known for pushing the boundaries of improv – and his audience – to the limits.

When he’s not busy blogging, you can catch London performing with Soulmates (below), or on his new podcast, Improv Movie Party. Click here to download episodes from iTunes. So far he and his pals have dissected and reimagined The Avengers, Prometheus, John Carter (now there’s a challenge) and more. Can’t wait for their take on The Dark Knight Rises.
