Very old american movie inquiry

[Fox]

I think i watched this when i was around seven or eight years old. Pretty good movie for its time and one of the few liveaction mech movies i can remember fondly.

G-Savior does not count.

Now that you guys mention it... I was wondering now if I watched it already.

It's just too familiar to me. I mean the mechs, but I can't actually remember anything.

I'm not sure if this is the one me and my sister watched before. I'll probably ask her about this thing after she goes home.

this movie probably came out by 1991-2 in the local channels so its possible.
