My girlfriend is trying to remember this movie and she just cant. All she remembers so far is that its a cheap 80s (maybe early 90s) movie, maybe made for TV, where a 10 year old boy and his younger sister get handed a mysterious piece of equipment (mysterious as in my gf doesnt remember what exactly it was or its purpose).
This object is given to them by a guy that works in a sort of video game store or something, asking them to take care of it. During the movie, for some reason, gangsters chase them. (maybe the boy witnessed something, the clerk being murdered maybe?)
Oh, and the boy carries around around a sort of gi-joe toy, which he talks to every now and then. (The toy is not alive or answers back, its not that kind of movie, from what i get)
(she recalls the kid calling the toy by its name; Jack.)
After a lot of imdb skimming, she sorta recognized the boy as "Joey Cramer", from the "Flight of the Navigator" poster. Turns out its not him, but might be a lookalke. I tried looking for the movies with ETs Elliot boy, since he also looks like this joey cramer.
Anyways, that it. Help me TL, you are my only hope :-)
