I need help with a movie title

I was watching the movie Ed Wood and it got to the part where he meets Orson Wells in a bar. They talk about their frustrations with movie making, and Wells mentions he is making a thriller and the company wants him to cast Charlton Heston as a Mexican.

So, any idea what this movie is/was?

During the bar scene with Wood, Orson Welles ('Vincent D'Onofrio (I)' ) complains of having to make a film with Charlton Heston cast as a Mexican, a reference to Touch of Evil (1958).
