Aliens in the Attic

When the kids are interrogating Sparks they ask him what his weakness is and one of the twins says "Water? Earth germs?". These are references to two well-known alien related films; in Signs (2002), the alien's weakness is water and in War of the Worlds (2005), their weakness is the common cold.

At the end of the fight between Ricky and Nana (at around 1h 02 mins), the control plug is knocked out of Ricky's neck, but at the end of the film, immediately after "The End" appears (at around 1h 19 mins), he is shown at Annie Filkins' house where Bethany and Tom use a controller to control him again.

The kids kept the gun from the aliens and Tom mentioned to Bethany that Ricky's car was broken down and he's not going anywhere. It's likely Tom and Bethany shot Ricky with the gun again and used controls.

Outtakes are shown during the end credits
