Question

what are the things which the actors do in the flim​

Answer 1

Oceans Brad Pitt

There are tons of lists on the internet exploring movie directors and their associated "trademarks", but there aren't quite as many dealing with the actors in the frames of said movies, who you might not have realised are also fond of repeating the same tried-and-tested tricks.

Whereas movie directors are probably more conscious in their attempts to insert their fingerprints (Steven Spielberg's fondness for shooting stars, for example), it's quite possible that some of the world's most famous actors aren't actually fully aware of their own reoccurring idiosyncrasies.
