The easiest way to think of this is to compare the changing acting styles of John Wayne and Burt Lancaster.Robert Crawford said:Now, that's funny!
When you watch Lancaster in Vera Cruz (1954), what is clearly lacking in acting technique is made up for in toothy grins. and posturing for the camera. Twelve years later in The Professionals (1966), he has now learned his trade and can completely inhabit the role – what you see on screen is a rounded believable characterisation with a Director who only made two Westerns .
Watching Wayne in Hondo (1953), here is an actor who has already produced a number of rounded acting characterisations in Westerns for John Ford, and Howard Hawks. Although the direction of Hondo is occasionally sloppy and it’s not a great film, the characterisation from John Wayne of Hondo Lane is believable. Contrast that with the John Wayne of fourteen years later in The War Wagon (1967), where any acting technique is replaced with goofy grins and mugging for the camera.
It’s like Wayne’s acting abilities went into full reverse after The Searchers.
So yes, John Wayne made a few fine Westerns*, but too often his films are of a “cowboy icon” having a good ‘ole time with his buddies.
