All of these films are from the early 80s or possibly late 70s.

The first film I can only recall two scenes: one where an evil lady puts a huge beetle under some guys skin and another after the guy gets the bug out he’s taunting her from afar “I got your bug out!”

The second film had something to do with body doubles. The only part I recall is a woman relieved to see her boyfriend/husband safe, saying she missed him or loves him and he responds “Even the mole on my arm?” Some kind of Creature comes out of his mole and gets her.

Last one I can only recall a scene where you can see someone talking to a doctor or surgeon, whose hands wearing rubber gloves can only be seen. He cracks his knuckles loud as hell.

Thanks in advance!!
