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.

So in my country traditional dish is carp with potato salad. Usually we go to short trip around, return at 16:00 and start preparing it. After dinner we open the presents, watch some fairy tale and go to church. I am atheist but at least I can tell that I periodically visit church, nobody needs to know that my period is 1 year.
