Sort of a wasted opportunity. They could figure other ways to use twins where people don't immediately leap to some mundane conclusion that undermines the novelty. I didn't hear a single observer say "it's like a mirror!" They just assumed there was a gathering of twins somewhere nearby.

Better use of twins would be to have people interact with seemingly the same person in impossible ways. Like have one twin getting onto a subway train interact in some way with someone getting off the train ("Got change for a dollar? or something equally normal). Make sure the person sees the twin leaving on the train. Then have the other twin waiting to emerge from a corner within a few seconds and interact with the person, preferrably in exactly the same way as the first twin did. That would leave people scratching their heads.

Agreed. Here is one where it is executed perfectly:

The setup took a huge effort though...

Anybody else see Stone & Stone?

illusion: failed!

A moving object like a subway car in transit would give the illusion away easily because the constant swaying and attempts to stay balanced by the riders. Each involuntary movement might be different between twins.

You know i noticed how there werent any black twins, though plenty of reaction shots from them. Not pulling a race card or anything but i wonder if its even more rare among black couples to have identical twins? Or what if its a mixed couple?

Hay-Zeus Crisco, am I the only person here that wants to eat a shitload of mushrooms and haunt this subway concern all night??!!! Put some midget triplets and a family of octuplets dressed as gnomes in that 'lectric freak tube and let's ride.....

For once I have to agree with choggie here...
