Cromwell kept showing up on the Amazon Prime "recommended for you" list, and it was free, so I watched it. This is the 60's Richard Harris one, in case there's some other one people might get it confused with. Not so good. Really clunky historical adaptation, subpar writing, tons of overacting. Skip it.
I mention that one because it led me into The Wild Geese. Interesting (1978) film. It's about this band of mercenaries Richard Burton puts together to attempt to rescue a deposed President of an African nation. Very 70's tone and production quality. The Joan Armitrading theme song stuck out to me from the outset as a sort of mirror universe James Bond theme, with the opening credits sequence also seeming like a mirror universe James Bond opening credit sequence, at least stylistically (note there were no prancing silhouettes of nude women). It's hard not to make a James Bond connection because, well, Roger Moore makes up the 2nd third of the main casting triumvirate, with Richard Harris being the final 3rd. Moore is pretty much a slightly (very slightly) grittier James Bond in this one, though he doesn't have quite as many scenes as Harris or Burton. Harris is a sort of egghead everyman, he really didn't have ton to work with here.
All three are nearly laughably too old for the physicality demanded of the action sequences, even given the premise that these mercenaries are over the hill to begin with. But they literally soldier on as best they can.
It's a bit of a 60's/70's trope film in the line of Dirty Dozen, Where Eagles Dare, etc. - a bunch of misfits, led by a few morally tortured geniuses, get sent on an impossible mission, knowing many won't come back alive, macho bonding ensues (or is revived from past relationships), resulting in manufactured heartbreak when said not coming back alive manifests. The ketchup blood packets were not spared.
The racial relations underlying theme gets put front and center in very heavy handed ways on multiple occasions, sometimes awkwardly inserted into scenes that didn't really lend themselves to that line of dialogue. I think the theme belongs in the film, I just think it could have been handled a bit less clumsily.
Most punches are telegraphed pretty well.
It may seem like I didn't enjoy this film, but actually I did. I think ultimately it was due to Richard Burton. Some may not like his particular style, but I think he's one of the greatest actors I've ever seen. In this role, it could have gone horribly wrong if someone else had taken it, probably going over the top and making it pure camp. But Burton is almost uniformly subtle and grounded throughout. It's worth seeing just for his performance. I wouldn't call it a must see overall though.
Oh, also Frank Finlay has a cameo, whom I really enjoy. I think, for a guy who was part Irish, his Irish Catholic priest tended a bit too much toward caricature, but I still got a kick out of him showing up.
