Gremlins
Inventor Axton picks up a cute, fuzzy Mogwai as an exotic pet for his teenage son for a Christmas present, with only three catches: don't expose it to bright light, don't get it wet with water, and never, ever, feed it after midnight.
Naturally no one pays attention to these short and easy rules, resulting in mayhem with reptilian Gremlins (Mogwai spawn) taking over the small town they inhabit.
Howie Mandel played the voice of Gizmo; Steven Spielberg also made a short appearance (in the inventors' convention sequence with sci-fi icon Robby the Robot).
Gremlins 2: The New Batch
In this sequel to the original Gremlins takes place shortly after the Chinese man takes Gizmo back. We've come to learn that the Chinese man is being forced out of his business by what appears to be a very bad Donald Trump clone (John Glover).
After being run out Gizmo escapes to wander the town, until he is caught by a team of twin scientists and brought back to their lab (coincidently the building belonging to the afore mentioned Trump clone). In an unforeseeable accident the scientists not only lead to getting Gizmo wet, they also expose the spawn to chemicals that give them all sorts of new abilities... Even that to talk...
Not to spoil it for you all, there is a bathroom wedding... Too bad it's not exactly human... At least, not half...
