Off-topic as it may be, I'd be happy to.
I haven't seen many 30s Hollywood films yet, so I'm open to changing my mind. Those I've seen (mostly the Universal monster movies which are considered classics of the genre) were vastly inferior to 1920s films from the country, and it's often claimed that early sound film was a downgrade from silent film when it comes to pacing and cinematography.
Yeah exactly, early sound films were very obviously a downgrade in many aspects, but that's mostly solved by 1930. And the Universal monster ones are certainly far from the best films.
If you give me some recommendations for 1930s Hollywood films, I'll be sure to put them on my list. I watch one film every week with a pal from the US, and we love discovering great old stuff. We started out with 1980s B-movies over a year ago, and at this point we've seen a couple of 1940s noirs and 20s silent films (mostly German, some Swedish and Danish, we got an American one starring Douglas Fairbanks scheduled in 3 weeks), both of which we quite enjoyed. Maybe we just had bad luck with our picks for 1930s US-made films so far.
Nice, Douglas Fairbanks is the GOAT, you can't go wrong with any of his swashbuckling films. Now for 30's stuff, I assume I needn’t mention stuff like Gone with the Wind, The Wizard of Oz, Stagecoach or the Marx Brothers' and Chaplin’s ones.
It'd certainly be worthwhile to watch
The Public Enemy (1931) +
Scarface (1932) and
I Am a Fugitive from a Chain Gang (1932), the grandfathers of the modern gangster and prison genres respectively.
I think you’d be very amused with the very good
The Big Trail (1930) starring a young John Wayne, for one of the antagonists is 100% one of the characteristic guards from Thief voice wise.
There is the
The Trail of the Lonesome Pine (1936) adaptation that I really liked which is I believe the first outdoors Technicolor film.
You have Errol Flynn (the discount Fairbanks) in films like
Captain Blood (1935) and
The Adventures of Robin Hood (1938) (themselves retreads of Fairbanks’ films) which are very good nonetheless.
I believe you have to check out Leo McCarey, especially
Make Way for Tomorrow (1937) - I will dare say equally great to the one it inspired (Ozu’s Tokyo Story) - and
The Awful Truth (1937) - a very smart comedy with the incredible Cary Grant. Speaking of Grant, you have a lot of great comedies like
Holiday (1938) and the archetypal screwball comedy,
Bringing Up Baby (1938).
I assumed you’ve seen/are aware of Stagecoach, but another great John Ford film is
The Informer (1935), concerning the Irish War of Independence.
Depending on how you feel about von Sternberg or Dietrich, they made their best films in this decade, like
The Scarlet Empress (1934).
It Happened One Night (1934) is a true classic, a pre-Code comedy by Frank Capra.
For animation I can’t recommend the Fleischers’ Betty Boop output enough, especially those featuring Cab Calloway, like
The Old Man of the Mountain (1933) and
Snow-White (1933).
My favourites though are probably the musicals. Anything by choreographer Busby Berkeley is unsurpassed to this day, especially
Gold Diggers of 1933 (1933, duh
) and my absolute favourite,
Footlight Parade (1933), a musical comedy with incredibly sharp, fast dialogue with the always excellent James Cagney and some insane musical numbers by Berkeley. Speaking of Cagney, besides this and the aforementioned The Public Enemy, he’s also in
The Roaring Twenties (1939) by the great Raoul Walsh. One of my other favourite musicals are the singing musicals with the amazing Maurice Chevalier, the top ones imo being
Love Me Tonight (1932) and
The Merry Widow (1934). Speaking of Ernst Lubitsch, this decade also has his top films, great comedies including
Trouble in Paradise (1932),
Bluebeard's Eighth Wife (1938) and
Ninotchka (1939). And to close with the dancing musicals, you have to indulge in the unsurpassed Fred Astaire, with his top one being…
Top Hat (1935).
Ok maybe I went a little overboard, but these are all imo
great films, there are even more good to great Hollywood films from this decade, and that’s just ones I’ve personally watched.
edit:
Some of the essentials from after the Hayes Code started:
My Man Godfrey
After the Thin Man (sequel to pre-code The Thin Man, which is also essential)
I can't believe I did my man William Powell dirty like that by forgetting to include these, but yes.
