Dear Mr. Watterson is a 2013 American documentary film directed by Joel Allen Schroeder, produced by Christopher Browne and Matt McUsic, with Andrew P. Waruszewski as the cinematographer.

After the first fundraising campaign, the filmmakers interviewed Berkeley Breathed, Lee Salem, Stephan Pastis, Jef Mallett, Dave Kellett, Charles Solomon, Seth Green, Keith Knight, Jenny Robb, Tony Cochran, Andrew Farago (Cartoon Art Museum), Joe Wos (Toonseum), Jean Schulz, Jan Eliot, Bill Amend, and more.

By digging deeper, it has become a better film.The film began with Schroeder interviewing fans of the strip to better understand the cultural impact it had.

The filmmaker did not seek to interview Watterson knowing his reclusiveness (the artist was invited to the premiere, but watched the DVD instead).
