All the ones I've seen open from the right. Same as all(as far as I know) Schweizers. Some of them had the double spring canopy closure on both sides so opening it from the left at least from the inside should work(not sure if there would be fuselage/canopy frame interference.)
When they filmed the remake they rigged the Duo to open the wrong way on the ground as well. Hollywood must think we get on our horses wrong.

I think it has more to do with what the actor/actress feels is their "good" side.
