An all time great movie.

Rating: 10/10 (31 January 2018)

I do not have much unique information to add to review of this all time great movie. But consider this information: This movie entire length kept my interest and interest of my young adult son despite it taking place in only two room, has no slang, no violence, no typical action. In fact, HD Net movies channel rated it as "G" and I agree.
This is top 10 on imdb.com and one of Roger Ebert's Great Movies.
