HBO Max’s much-anticipated remastered debut of “Mad Men” was spoiled by several on-screen errors and mislabeled episodes.

Last month, Warner Bros. announced that it would remaster the show in 4K to give HBO Max “audiences and longtime Mad Men fans the opportunity to enjoy the series’ authentically crafted elements with crisp detail and enhanced visual clarity.”

The first four seasons of the show were shot on 35mm film. However, the sharper resolution didn’t distract people from the mistakes popping up onscreen.

During one Season 1 episode, crew members and a vomit bag are captured in a shot where drunken character Roger Sterling (played by John Slattery) threw up at the office.

In a Season 2 example, viewers were supposed to see character Peggy Olson (played by Elisabeth Moss) walking down a New York City street in the 1960s. However, watchers also saw a Mexican restaurant displaying a sign with a Los Angeles area code and an ad for cell phone SIM cards.

Lionsgate delivered the wrong versions of the episodes to HBO, according to The Hollywood Reporter, which added on Tuesday that the episodes were being swapped out.

“Mad Men” officially debuted on the platform Monday, but the show, produced by Lionsgate Television, aired originally on AMC from 2007 to 2015, with seven seasons and 92 episodes.

The show is set in 1960s New York and follows the plight of an ad executive named Don Draper, played by Jon Hamm, and an ad agency.

During its run, “Mad Men” became a crowd favorite, earning 116 Emmy nominations and 16 Emmy wins.

Viewers can still watch the unremastered version on AMC.

Representatives for HBO Max and Lionsgate did not immediately respond to HuffPost’s request for comment.
