PTB Like Horse Racing?

Watching the movie "Secretariat", and see a scene perfectly framed to show "33"-- at the top of a gate, sitting there for many seconds, laughing at us. There's no question this 33 was inserted into the scene, and framed, on purpose.

Looking at the wiki page for Secretariat, I see he was 533 kg and was also honored with a 33 cent postage stamp. Also one of his major race times was 1:33.
