(Richard Harrison) is one of the nicest American actors I have worked with. - Donald O'Brien

I always preferred those movies I would have a large role in. If I had to choose between a small movie with a big role and a big movie with a small role, I'd take the one with more screen time. It's not very satisfying for an actor to get work and then ending up on the cutting room floor.

The leading lady of this film (Yeti) happened to be Antonella Interlenghi, the daughter of Antonella Lualdi. The girl very obviously inherited her mother's beauty, but she had the silliest pseudonym I've ever heard. She called herself "Phoenix Grant". I mean, what kind of a name is this? It's just as if I called myself, say, Hyde Park Corner Montgomery. Or Hamburg Rommel, how about that?

Svenson taught me how to speak German in this film! I didn't know anything, and this guy, who used to be a Swedish ice-hockey player who went to Vietnam as a Marine, he stood there with me, coaching me things like `Bringen Sie die Gefangenen in mein Buro!' Williamson also was a very nice person. I had one wonderful scene in this movie, where I...I was outranking them, they are my prisoners, I walk in front of the prisoners, and I have to say something like, in a very contemptuous way: `Americans...Italians...Jews...Irish!' I felt like a traitor!
