Action (formerly known as Showcase Action) is a defunct Canadian English language specialty channel owned by Corus Entertainment. The channel was established as a spin-off of Showcase focused on action genre films and television series. Following a rebrand in 2009, the channel would eventually shift to general-interest, male-targeting programming. The channel was first launched on September 7, 2001; it was rebranded on April 1, 2019, at midnight ET as Adult Swim. ()
