A Midsummer Night's Sex Comedy (1982)

 

A wacky inventor and his wife invite two other couples for a weekend party at a romantic summer house in the 1900s countryside.

From memory: Light-hearted and inconsequential, Woody Allen plays around with Bergman's Sommarnattens leende, all very well made, good dialogue and a capable cast, it's enjoyable but without much substance.

Halliwell*: "Subdued, melancholy and rather uninventive Woody Allen variation on Smiles of a Summer Night." 

Maltin***: "SMILES OF A SUMMER'S NIGHT, Woody Allen-style; a quirky, entertaining diversion...Appealing cast...,exquisite Gordon Willis photography."
