IN CASE YOU MISSED IT: Catherine O'Hara to appear posthumously in Martin Short documentary.

The Schitt's Creek actress will make an appearance in the upcoming Netflix documentary, "Marty, Life is Short." Catherine and Martin first met in the early 1970s while they were both on Toronto's improv scene. "I feel like he could improvise to eternity. Couldn't he?" she is seen saying in the trailer for the show. The documentary is described as using "beautiful, intimate, never-before-seen" archival footage to illustrate Martin's life, career and relationship with grief. "In life, sometimes you hit a green light. And sometimes, for no reason, it's red," he's heard saying in the documentary about grief.
