The endearing post attracted attention from fans and fellow celebrities, including Rachael Leigh Cook, who wished him happy birthday and dubbed the day \"Christopher Lloyd Day,\" and Janelle Monáe, who called him \"a legend.\"

Lloyd recently made headlines when he reunited with his \"Back to the Future\" co-star Michael J. Fox at New York Comic Con earlier this month.

\"The chemistry was there from the first scene we had,\" the actor said during a panel of working with Fox on the beloved movie trilogy. \"It remained that way for three movies and it hasn't gone away, by the way.\"

Of the reunion, which took place 37 years after the first \"Back to the Future\" film, Lloyd reflected on Instagram, \"I cherish these moments! Thank you to @newyorkcomiccon, my dear friend @realmikejfox, and most importantly all you wonderful fans who show up year after year. This is all because of you! This is heavy!\"
