I'm not perfect either, because they did get the director's name right, I guess i got my eyes crossed, because I thought that they said the first name was Jack, instead of Frank. The only Jack in the movie is Jack Larue, which I didn't even recognize until I Googled a picture of him, and even then I'm not sure that I do now. I thought it curious that this actor was listed on the cover credits, when Adolph Menjou was not, even though he was a very prominent actor in his day, and played the side kick role to Gary Cooper and appeared throughout the movie.
I have seen a lot of other movies that touted some actor that had an obscure role in a movie before, but that was due to the fact that they later became stars themselves. I do not think that I would consider Jack Larue a star.
