I'll just leave this here.

I always thought it was because Robin Williams is a fourth wall breaking son of a bitch

I would respect this but I'm nitpicky for details... Third century was 200-300 A.D. And he's an all powerful genie, he may not be able to leave his lamp but he could always look at what's going on throughout the world using his all powerful magic.

This is stupid. Stop trying to over analyse Disney movies

Nope, sorry. This has been talked about by Disney, and they say as he has 'phenomenal cosmic power' and all, he has the ability to transport himself between different points in time, hence, 'so third century'.

There was a BC you know!

It's good that there are still tigers in the future.

Rip robin Williams

Aw geez. It's a damn movie for kids. Stupid hipsters trying to relive childhood
