In 2015, Herlihy co-wrote (with Sandler) the Western comedy film The Ridiculous 6, distributed by Netflix. Despite being universally panned by critics, on January 6, 2016, it was announced by Netflix that the film had been viewed more times in 30 days than any other movie in Netflix history.
Herlihy returned to Saturday Night Live for one episode in 2015, to work with Tracy Morgan on a recurring sketch they had created in the 1990s, Brian Fellow's Safari Planet. The episode was nominated for an Emmy Award for outstanding writing, and won a Writers Guild Award for Outstanding Writing for a Comedy/Variety sketch series.
