Not much like favourite movie but some interesting ones. I recently listened to podcast about Czech cinematography and there are some worth watching.

"Marečku podejte mi pero" is fun comedy with lots of puns and remembered lines. It stars first Czech professional actor and some that are active to this day.

If you want something from the same guys but more serious "Nejistá sezóna" and "Kolja" (this won Oscar for best foreign film) is also worth watching.
