Both actors can thank their career paths for being able to curb their smoking habits, according to Patterson when he spoke to The New York Times about his time on set. 

The 62-year-old actor revealed that due to the fast-paced dialogue on set, he and Graham had to quit smoking in order to catch up.

The comedy-drama, which ran from 2000-2007, had scripts that were "were 20 pages longer than the average hourlong series", according to The Times, and director and writer Amy Sherman-Palladino required the actors to read their lines word for word.

In order to keep up with the swift dialogue and intricate scripts, Patterson said he and Graham had to promptly quit smoking just to keep up.

"She needed her wind," he said, referring to Graham, "I needed my wind."

Patterson also said that there were often rewrites, and that "the volume and pace of the dialogue" kept them on their toes, including a time a 10-page scene was given to them at 6:30 a.m. before their shoot.

"Lauren and I were sitting in the makeup chair," he recalled, "We looked at each other with this abject terror, and then we got to work."

Earlier this year, Gilmore Girls celebrated its 20th anniversary.
