In search of a short cinematic movie from ww2.
Here are the details I know:

>about 5~10 min long
>the video itself has a grey filter over I think or is generally more shadowy
>I think the movie is from Russian source
>scene takes place in ww2 in a circus
>Russian soldier walks into centre of the circus finds juggling balls and start playing with them
>meanwhile comes a German soldier on the top of the audience stares and aims at him.
>decides not to shoot and watches him until he makes sound
>Russian soldier notices
>picks up weapon
>stare contest begins
>eventually nothing happens and they make some funny mimics and later leave without harm
