12 Actors Who Hated Being On Star Trek
11. Jeffrey Dean Morgan
Negan was in Star Trek Enterprise, minus Lucille. However, thanks to the show, he almost quit acting altogether.
Jeffrey Dean Morgan appeared in the third season of Enterprise in the episode entitled Carpenter Street, also starring guest star Leland Orser. The heavy makeup required for the Xindi Reptillian role was overbearing and claustrophic, which meant that filming was a miserable experience for him. Add to that, the role itself was small enough that there wasn't even any legacy to be had in putting himself through that much pain.
Morgan later admitted that there were times he would cry in the evenings from frustration, fatigue and bitterness. Once production wrapped on the episode, he had decided that acting wasn't for him. However, thankfully he would take time and change his mind, eventually becoming the hugely successful Negan on the Walking Dead.
