A newspaper showing "Carl Sagan"

While in Hill Valley in 1931, Doctor Emmett Brown used the alias "Carl Sagan" and his name appeared in the Hill Valley Telegraph.

Upon returning to 1931 from 1986 in the alternate timeline where Emmett Brown and Edna Strickland controlled Hill Valley as first and second Citizen Brown, Marty convinced Citizen Brown to use the alias. Marty later used the alias over the phone to get Edna Strickland to confess to being the speakeasy arsonist.

After Citizen Brown was erased from existence, Doc resumed the alias for the remainder of the time he was in the past.

In 1986, when Marty McFly turned on the television in Doc's garage, the voice of Carl Sagan could be heard.

Behind the scenes[]

Carl Sagan was a fan of Back to the Future, and once told Robert Zemeckis and Bob Gale that he thought Back to the Future Part II was "the best movie ever made based on the science of time travel."[1]

Carl Sagan's 1985 novel Contact was adapted into a 1997 movie, directed by Robert Zemeckis.

Carl Sagan appeared as himself in The Earth Day Special during 1990, which also had Christopher Lloyd appearing as Doctor Emmett Brown.
