MechWarrior 2: Resource Forum

I think that this is as close as your going to get to a mech movie besides Transformers.

unless, on of these studetns becomes a big time producer someday and remembers his class project.

There were some other videos, but I'll post these funny ones first, though they're not exactly BattleTech:

A Gentleman's Duel
Nazi Mechs: When Robots Attack (part 1)
Nazi Mechs: When Robots Attack (part2)

They're rather big ...

They had a animated battletech but I thought it was not good, a movie with a good mix of fast action and plot may work but getting it started is tough
