Mark Dodson, who played roles in STAR Wars and Gremlins, has died. He was 64 years old.

The star is said to have died while at a fan convention in Evansville, Indiana, which is about 170 miles southwest of Indianapolis.

TMZ says Mark had a “massive heart attack” while he was sleeping at his hotel in Indiana.

His daughter Ciara told the news outlet that her father had died and that he was in the area for Evansville Horror Con 2024.

She told everyone that her dad “always made me proud.”

Mark was going to be at the event on both Saturday and Sunday.

On the talent list were also Bam Margera from Jackass, Jason Hawes from Ghost Hunter, and Sean Whalen from Twister.

Mark had planned to do paid photo ops and autograph sessions with fans, and on Sunday he was also going to be on a panel.

Mark said in the caption of an Instagram post a few days ago, “Come see me this weekend in #Evansville #horrorcon #starwars #gremlins.”

Since he was a child, Mark did voice work. He was best known for his work on the Gremlins movie series.

To start, he did the voice of Salacious Crumb in Star Wars: Return of the Jedi for the Star Wars movies and video games.

Mark could be heard most recently as Adam Hamada in the Ghostrunner II game, which came out last year.

“His unique voice and sound were added to every character and script he touched,” Mark’s rep told the news source.

We are heartbroken to announce the sudden death of Mark Dodson last night,” Evansville Horror Con wrote on its Facebook page in honor of the actor.

“Mark was not only a talented voice actor but also a cherished member of the horror community,” they said. “During this very sad time, our thoughts and prayers are with his family, friends, and fans.

“We hope that you can take a moment out of your day to reflect on the joy and laughter that Mark brought into the world His legacy will live on through his work.”
