Was watching the movie today, what type of bow would that be considered, a short recurve or is this a Rambo custom?

Rambo scene

It's an old compound of some kind.

Arrows are 6 inches longer than he needs. Prolly wouldn't do to use a kid's setup that fits his frame

Almost looks like the same bow from the original movie. The original was a Hoyt Ram Hunter - later named the Rambo after the movie. I had one, nice bow for the times.
