In December of 2015, Bad Lip Reading simultaneously released three new videos, one for each of the three films in the original Star Wars trilogy. These videos used guest voices for the first time, featuring Jack Black as Darth Vader, Maya Rudolph as Princess Leia, and Bill Hader in multiple roles. The Empire Strikes Back BLR video featured a scene of Yoda singing to Luke Skywalker about an unfortunate encounter with a seagull on the beach. BLR later expanded this scene into a full-length standalone song known as "Seagulls! (Stop It Now)", which was released in November 2016 (eventually hitting #1 on the Billboard Comedy Digital Tracks chart . ) As of December 2018, the "Seagulls!" video is Bad Lip Reading's most viewed YouTube upload and most popular musical production. In the song, Yoda sings to Luke Skywalker about the dangers posed by vicious seagulls if one dares to go to the beach. Mark Hamill, who played Luke Skywalker in the Star Wars films, publicly praised "Seagulls!" (and Bad Lip Reading in general) while speaking at Star Wars Celebration in 2017: "I love them, and I showed Carrie [Fisher] the Yoda one… we were dying. I showed it to her in her trailer. She loved it. I retweeted it… and [BLR] contacted me and said ‘Do you want to do Bad Lip Reading?’ And I said, ‘I’d love to…’”. Hamill and Bad Lip Reading collaborated on Bad Lip Reading's version of The Force Awakens, with Hamill providing the voice of Han Solo.
