Depending what you mean by "Classics",
Kanopy has some classic films from the 20s, 30s, 40s, 50s.
For those that aren't familiar, Kanopy is free with your Calgary Public Library card (and many other libraries). It has some recent independent films, classic films, world cinema, documentaries. Pretty much everything except Hollywood blockbusters. If you are bored of cycling through the same posters of Netflix movies, you can browse the thousands of titles on Kanopy and at least feel like you are cultured because you briefly considered watching an indie or even a non-English movie.
With the holidays and holiday parties coming up I think it is the perfect time to brush up on your pretentiousness.
"Have you seen
A Star Is Born?"?
"The 1937 film starring Janet Gaynor and Fredric March, the first colour film nominated for Best Picture? Why, yes what a wonderful film."
