Takes and double takes

Take. The filming of a scene without interruption.

In filmmaking, a ‘take’ is a scene shot without interruption.

On the other hand, a double take is a delayed reaction to an unusual remark or circumstance. For example, if you walk down the road dressed as Darth Vader, a passerby might glance at you, continue on their way, and then a second later, stop and turn around in surprise.

Double takes are used as a comic device in the cinema. In the clip above from Dinner at Eight, when Jean Harlow mentions she's reading a book about the future, Marie Dressler does a fabulous double take.

An interesting variation on this is a spit take, in which the double take causes the character to spit out whatever they are drinking, like this talk show host.
