Blooper

After Tomas the window-washer slugs back the wine offered to him by the Communist Party official's wife, the wineglass refills as he sits down on the chair next to the sideboard.

When Tomas drives to the spa town to perform an operation in the beginning of the film, he is shown driving a light blue sedan with an aluminum roof rack. After meeting Tereza and then leaving to drive back back to Prague, he is seen driving off in a car of a darker shade of blue with no roof rack.

The pig that attends the wedding is relatively newborn. When Tomas and Tereza return to Czechoslovakia after a stay in Geneva and a lengthy stay in Prague, they move to the farm where the farmer proudly claims the pig has grown. By this time, the pig would be very much bigger than the pig on the cart. Pigs typically grow hundreds of pounds in the first 4 months of life.

When Tereza is challenged in the bar by the drunken youth, the bottle of Orange disappears and then reappears.

When we first see Tereza taking photographs in Prague she is shown wearing her wedding ring, yet she and Tomas are not married at this point in the story.

There should be much more cigarette smoking in 1960s eastern Europe. Without a doubt, Tomas, Tereza, and Sabine would be regular smokers, and background characters would smoke too, especially at parties and protests.

During Sabina's final monologue at the end of the film, Lena Olin's Swedish accent is quite noticeable.

When Tereza goes on her first photo foray into downtown Prague the soundtrack features a woman singing a Czech version of "Hey Jude," the original Beatle version of which was not released until August 26,1968 - the week after the Soviet invasion of Czechoslovakia.

While nowadays, many people in the Czech Republic wear wedding bands on the left hand, back in 1968 they would have worn them on their right hand regardless of their political stance. Both of the main characters are shown in the movie to wear their wedding bands on the left hand as they would have in the U.S., not Czechoslovakia.

The action takes place around the time of the Prague Spring (roughly January to August 1968), but the car that Tomas uses in his first trip (Skoda 100/110) was not built until 1969.

The vintage camera used by Tereza and Sabina in their photo-shoot is a PRAKTICA LTL and it was not released till 1970.

DX-coded film was not invented until the 1980s.

When Teresa is taking pictures of Sabina, the movie camera is sometimes reflected off of the lens of the photo camera.

Mephisto the Pig, consistently referred to as "he", is a sow, as can be seen frequently, but particularly when the group enters the inn for dancing.
