Just checked out Family Swap, a Freaky Friday type story only all the members of the family swap bodies. There are two gender swaps. First, the teen-age son swaps with his older sister. Then, the father swaps with his wife.
It’s a family film, so while there are a few fun gendery scenes (the teen-age son charges another kid 10 Euros to see his boobs) it’s mostly about family more so than gender. However, the father while in the wife’s body does sleep with her lover (off-screen) and he even considers running off and becoming the other man’s mans wife.
One difference between this and other such movies is that the swaps don’t stop. We are told at the end that the family keeps swapping, and we do see the father at the end swapped into the body of their 8 year old daughter.
