I think every age has a medium that talks to it more eloquently than the others. In the 19th century it was symphonic music and the novel. For various technical and artistic reasons, film became that eloquent medium for the 20th century.
In Hollywood there's a great openness, almost a voracious appetite for new people. In England there's a great suspicion of the new. In cultural terms, that can be a good thing, but when you're trying to break into the film industry, it's definitely a bad thing.
