I mean, I'm not sure how it is in your household, but jumping tables wasn't really a common thing with us. If I'm honest, if you asked me to jump a whole table, I think I'd hurt myself.
This got fixed in the 4k releaseI have no idea how for so many years I didn't notice the motorcycle stuff in T2, but now I can't unsee it every single time I watch it. It's kind of ruined that entire sequence of the movie for me, or at least tainted it. But yeah, came to this thread to point out that one and I see I am already very late to the party.
No, that was not intentional, they just had to use stunt doubles for many shots rather than CG Smiths.
I'll have to rewatch it because I distinctly remember those doubles being EXTREMELY obvious, and I seem to recall actual talking parts by some of them too? It never crossed my mind it wasn't intentional because they very visibly show the "fake" Smiths a lot, not doing anything to hide them.
