Toadfish Monastery

No ships but relationships and no whales just wails.

This looks intensely creepy and I like the style.

Yeah, there are a few creepy moments

Fiddler on the Roof?

Are the ladies Russian?

The Cherry Orchard, Anna Karenina.

Just making silly guesses. The harlequin stumps me.

The Puppet Master 2 ?

There is a Russian connection but it is not a specifically Russian-themed movie.
Parts of the film take place in several diffeent European countries.

The scene in the next picture is on a Russian location, though.

Btw, it is a period piece, not 'modern' people putting on costumes in-universe for whatever purpose. No guarantee for complete lack of anachronisms (of the type 'this item got introduced 20 years after the setting period').

HMS Pinafore

Nope. But some great music nonetheless.

Is it that one where they go up to heaven?
