Though there is plenty of action, enough to keep a Western addict (including me) happy, this is really a comedy.
Jack Hoxie had trouble with delivering dialogue in previous films -- see, for example, my review of "Law and Lawless" -- but, however he did it, whether extra care by director Lew Collins or private coaching, he handled his part here like a pro.
He was a little "aw, shucks" when that was needed, and he was "you better smile when you call me that" if that was called for.
He was very ably supported by two character actors who just shone, and who just out-did themselves in their roles here: Harry Todd and Ben Corbett.
Even in their roles as drunks, they were right on target, not overdone and fully believable.
Playing the bad guy was the inimitable Slim Whitaker, here billed as Charles Whittaker. Under whatever name, and billed or not, he was a wonderful actor and made dozens of B Westerns even better by his presence.
Female lead is a very lovely actress named Kaye Edwards, who has no other credit listed here at IMDb. What a shame. She was quite good in this part and no doubt should have had a successful career.
William Burt is a scene-stealer as the irascible store-owner, and a superlative actor to carry off such a part.
Still, with all the talent in this excellent cast, the real star is the script by the legendary Oliver Drake. I can't think of a better one by him -- or by anyone else. He skillfully combines all the elements, including a hilarious automobile, into one of the most entertaining B Westerns I have seen -- maybe ever.
"Trouble Busters" is available in a good print at YouTube, compliments of those doubly wonderful folks, www.westernsontheweb.com, one of the greatest sites on the Internet.
Seriously, "Trouble Busters" is a real find, and I urge you, if you like B Westerns, please see this one.
