In a conversation with a movie buff friend recently, my friend mentioned that he once owned a 35mm film of nothing but Humphrey Bogart bloopers. Well, you know what they say: If it's on tape, it's on YouTube. And sure enough, I found some examples. Here's a roughly 4-minute reel of Humphrey Bogart bloopers, which shows Bogie's reaction to blowing his lines was sometimes laughter but more often a sharp "goddamn!":
Where do these come from? From 1936 through 1947, blooper reels were compiled by "The Warner Club." That was an organization comprised of Warner Brothers studio cast and crew members. The club met annually for a dinner, and the blooper reels were shown during those dinners. The blooper reels were known as "Warner Bros Breakdowns" or "Warner Bros Blow-ups," and eventually made their way out into the public (these would be the 35mm films that my friend once owned).
You can find the full Warner Club clips on archive.org.
As for the Bogart blow-ups and breakdowns clip above, YouTube user afrenchindublin took all the Bogie* bloopers from the Warner Club clips of 1936, 1937, 1938, 1939, 1940, 1941, 1942 and 1944 and edited them into their own video.
(*Is it "Bogie" or "Bogey"? Varies from publication to publication, person to person. But Bogart himself spelled it "Bogie."
