If you're an Alfred Hitchcock fan, which I am, you'll notice he works with a lot of the same actors/actresses. For example: Grace Kelly, Jimmy Stewart, Cary Grant, Farley Granger, Bruce Dern, Tippi Hedren, Jessie Royce Landis, Leo G. Carroll, to name just a few. I've seen interviews with Mr. Hitchcock and some of these actors and they either love him or hate him. There doesn't appear to be any middle ground.
Question: In the opening credit sequence from the movie North by Northwest, taxis and buses are shown behind the credits. When Alfred Hitchcock makes his typical cameo, he's trying to board a green and beige bus, but in the credits, the city buses shown are red and beige/yellow. Is this a blooper (albeit minor one) or do some cities have buses with different color schemes serving the city at the same time? I don't have the answer but I'm curious if any other person has noticed this.
