...damn, you're in for a treat (not much detail on DVD description at the time of writing this - I watched the very recent US release, no frills, no restoration but perfectly watchable copy, apparently made from the best print available).
Ashby's The Landlord is firing on all cylinders of a young fresh talent. It has its uneven moments and uncomfortable shifts in tone, and you can see how Ashby streamlined his output for his later better known films and gained more control over the content (although, I'd argue, at cost of some ambitious complexity present here). Some characters remind those of Harold and Maude - there is a touch of Hair &Being There too - but are more in more complex and multidimensional. Very few characters exist only to be laughed at here, for example unlike in Harold and M, that difficult shallow mother in the incarnation here is not all a monster. Life is messy, and the film has no problem with this although viewer might, especially when used to the simplified versions on the screen. The film also has some bravura sequences - watch out for a party sequence as the maincharacter vomits up his upperclass upbringing and ends up making one of life's big mistakes - and Ashby's talent in editing is clear.
Some scenes had me uncomfortable at times but when thought through, I realised that maybe I was just being slow to accept how things CAN be, and some political content is spot on in the context of its time even if we'd prefer to forget about how things came about in terms of equality of races etc. Life, people, and the way we are and operate hasn't gotten any simpler since this film was made. When did we lose our interest or ability to reflect this on film? This film deserves to become a rediscovered cult classic. I think it has just edged past Harold and Maude on my list of favourites - because of it's big messy heart, characters that you just have to forgive sometimes and the huge breath of fresh air, straight from our recent past.
