Mindwalk (1990)-not to everyone's taste (or p.o.v.), but what is ? It's 3 characters walking & talking about stuff, reminded me a tad of "My Dinner with Andre", only less dull & esoteric. All they do is walk & talk, but my interest didn't flag, watched it twice in a row. Sam Waterston, John Heard, & Liv Ullmann, as a politician, a poet, and a physicist. Ione Skye has cameo as Ullmann's daughter.
I quite liked (of previously listed films) Ghost World, Station Agent, and Freeway.
Other lesser-knowns (mid-to-late 90's):
A Map Of The World (Sigourney Weaver as woman accused of child abuse, David Strathairn as her husband, Julianne Moore as her friend). Wrenching & painful but great movie.
The Safety Of Objects (Patricia Clarkson as the older woman, Glenn Close as the mom of the younger man, played by Joshua Jackson). Another unhappy film, but it was richly textured & quirky.
