- Jeffrey is among the several cast members who starred in Frank Darabont's The Mist, along with Laurie Holden, Melissa McBride, Juan Gabriel Pareja, Tiffany Morgan and Sam Witwer.
- DeMunn requested to leave the The Walking Dead after Darabont was fired as showrunner and Dale was subsequently killed off.
- Prior to his character's death, it was reported that an unidentified cast member had asked to leave the show, but then had a change of heart, which many assumed to be DeMunn. However, when Chandler Riggs and Darabont confirmed that DeMunn left due to Darabont's firing, neither made mention of DeMunn changing his mind.
