15 Superhero Voice Actors Who Totally Nailed Their Characters

8. Phil LaMarr: John Stewart/Green Lantern

Phil LaMarr, much like Tara Strong too, has lent his voice to a tonne of animated projects over the years. He was Hermes in Futurama, Wilt in Foster's Home for Imaginary Friends, and has even had turns in Family Guy and a bunch of other projects on TV, film, and in video games too.

LaMarr may have voiced a few other comic book characters since taking on the part of John Stewart in Justice League, but it's still his best work in the genre. Indeed, the part of Green Lantern on Justice League is probably the character's most iconic iteration, certainly among the DC hardcore, and even, perhaps, among casual audiences too. For a generation raised on Dwayne McDuffie's Justice League, he is their GL. The thought of another Lantern in the role is just bizarre.

LaMarr's time spent as the Lantern of Sector 2814 was, for many, the definitive take on the character, with the actor's performance having undoubtedly benefited from the strong material the creators behind the series managed to produce. Here's hoping that any future big screen Lantern will brush up on JLU in preparation for their role.

Content Producer/Presenter

WhatCulture's very own resident movie guy, Ewan has been working in the content creation biz for over 10 years now, having started as a freelance contributor to WhatCulture Gaming all the way back in 2015. After graduating with a First-Class Honours in History from Northumbria University in 2017 (where he won a prize for a totally killer dissertation on the Watergate years), Ewan took on the role of Comics Editor at WhatCulture and quickly developed WhatCulture Comics into one of the biggest superhero-focused channels on YouTube. He followed this with a brief hiatus at Screen Rant in 2021, where he worked across the Gaming and Film sections as a writer and editor, before returning to WhatCulture as a Senior Content Producer / Presenter in 2023. He started his own podcast, We Love Dad Movies, in 2022, and has contributed several written pieces to the Eisner-nominated comics website Shelfdust as well. In his current role, Ewan incorporates his love of cinema, comic books, and history into written pieces and video essays for WhatCulture's Film & TV channel, as well as WhatCulture Gaming and WhatCulture Horror, with a particular focus on nineties-era Dad Movies, old school Westerns, and Golden Age Hollywood Noir. John Carpenter is his fave, and he thinks Batman Beyond should never have been cancelled. If that's your vibe, you'll probably like his stuff.
