Early Humphrey Bogart films

I would suggest using google:
"title (release year)"
You may see some are available to rent/buy online.
Then look under the shopping category and/or the video category.
In the shopping category you may need to add the word "dvd" to the search.

For example:

The shopping link shows dvds for sale.
And the videos link (under More) does show a full-length video that is probably in English (although sometimes they are overdubbed.)
