It's heartening to know, according to Stefanie Powers, that Holden and Schroder formed such a loving bond that Schroder grew up to name his two boys William and Holden.
And there's some interesing scenery here.
But the dialogue is such try-hard tripe. No two guys would act the way Holden and the other geezer yell at each other. Holden mutters to himself to explain to half-wit viewers, presumably, what he's thinking even though we've already figured it out.
And what's with Schroder? Is he spoiled or brain damaged.
Everybody in this movie yells.
Subtle as a sledgehammer and not very satisfying.
That said, Holden looks surprisingly good for a guy who would soon die in real life. It's a travesty he didn't live to make better movies or to retire to his property in Africa.
