MGM never had any idea what to do with its contract star, Laraine Day, other than cast her as Lew Ayres' girlfriend in the "Dr. Kildare" series. Other than that, they loaned her out. I'm not sure if she was still with MGM when "Tycoon" was filmed - I have absolutely no clue why anyone would think of her as a South American, but there she was, with black hair and her skin darkened.
I digress. "Tycoon" stars John Wayne, Day, Sir Cedric Hardwicke, Anthony Quinn, and Judith Anderson in a technicolor film about the travails of a) falling in love with the boss' daughter; and b) then having the boss make sure you don't have the materials to build your railroad, tunnel, or whatever else you're building. Seems a bit self-defeating and spiteful.
Filmed in technicolor, some of the shots are gorgeous, and some are hilarious - for instance, the South American town, which is a painted backdrop.
I actually like John Wayne when he's not in a western, and here, he's handsome and tough and brings some life to the proceedings. I've always been a fan of Laraine Day, and she's lovely - but a chimpanzee could have played her part. I understand Day's husband, Leo Durocher, was on the set most of the time and was jealous of John Wayne. Judith Anderson as her duena is very good and Hardwicke is dignified. Anthony Quinn, as he often was back then, was shown to great advantage in a supporting role.
It might have been a better film if it had been shorter - there's just too much down time in "Tycoon." The script is a bore. The explosions are good.
