"And the Institute sent me a little film footage of Kinsey himself preparing to do an interview for television to talk about his work, so that was quite valuable for me"

Liam Neeson is referring to the Institute for Sex Research, which was founded by Alfred Kinsey. Kinsey was a biologist and sexologist who carried out research study on human sexual behavior in the 1940s and 1950s. Neeson was investigating Kinsey for a function he was playing in a movie, and the Institute sent him a film of Kinsey getting ready for a television interview. This was a valuable resource for Neeson, as it enabled him to acquire insight into Kinsey's quirks and behavior. It also offered him a better understanding of Kinsey's work and the effect it had on society. Neeson had the ability to utilize this footage to accurately depict Kinsey in the film, and it was a crucial part of his research study.
