Twin Peaks

The series was originally to be titled "Northwest Passage"

At the beginning of the shooting of the second season, actress Sherilyn Fenn came down with a bad case of pneumonia, making headlines that the shooting of the series might be affected or that she might have to leave the show. As writer/producer Harley Peyton said in an interview: "It looked like it could give us some really serious problems. It turned out all right. She was tremendous and recovered rather quickly and came back sooner than she had to. We had different directors shooting each day and two directors shooting in a single day and, in fact, got all of her scenes done."

Creators David Lynch and Mark Frost assigned no episode titles, only episode numbers. When the series aired in Germany, titles were assigned, which were then translated to English. The episodes are untitled on the DVD sets, but the titled episodes appear on the official Twin Peaks CBS website when streaming the episodes.
