Annie Murphy is forever grateful for the laughs she got to share and lessons she learned from the great Catherine O'Hara. The actress passed away on Friday at the age of 71 following a brief illness. The news rocked Hollywood - and it absolutely devastated the cast of Schitt's Creek, many of whom took to social media or elsewhere to mourn her loss. Now, Annie, who played Catherine's on-screen daughter Alexis Rose, is breaking her silence on the tragedy.
