Seth Rogen's 'Home Alone' shock

(CNN)Seth Rogen's mind has just been blown.

Rogen has been rewatching holiday classics in recent days, and he was shocked to learn that the black and white movie Kevin McCallister (Macaulay Culkin) watches in "Home Alone" was never actually made.
"My entire childhood, I thought the old timey movie that Kevin watches in Home Alone (Angels With Filthy Souls) was actually an old movie," Rogen tweeted.
