The DC TV shows on the CW are packed with good singers. Grant Gustin from “The Flash” and Melissa Benoist from “Supergirl” both got their big breaks on “Glee,” while “Arrow” star John Barrowman has an extensive theater background. But one actor is saying no to a musical episode: “Arrow” star Stephen Amell.

At Wizard World Philadelphia, a fan asked if he would ever consider doing a musical episode. “You know what? We will, but only if Oliver dies in Act One, ‘cause everyone else can sing,” Amell joked Saturday.

Watch his reaction in a video below:

The fan suggested that he do it for charity, and Amell didn't shoot down the idea of singing for a good cause. But he still doesn’t want it broadcast on television.

“I’ll agree to a venue in Las Vegas, New York, or heck, even Philadelphia to do a live show,” Amell said (via Movie Pilot). “A musical version of ‘Flash’ and ‘Arrow’ — but no musical episode! We'll get John and Grant, but I am literally the worst singer out of everybody.”

It looks like Amell is sticking to his decision on this one. The “Teenage Mutant Ninja Turtles 2” star shot down the idea Friday. “No. I’m out! I’m the first one,” Amell told MTV. “I get to draw the line, and I draw the line at musical.”

Next year’s four-show crossover, which includes “Arrow,” “The Flash,” “Supergirl” and “DC’s Legends of Tomorrow,” is going to be hard enough without dance numbers. The CW announced that moving “Supergirl” to the network will allow their biggest crossover event yet, but Amell is still wondering how that will even be possible.

“They have to show me how they’re going to do this magical four-show crossover,” he added. “It was hard enough when it was two shows and mixing in ‘Legends’ a little bit. To make it four shows? I’m dumbfounded.”

The writers have plenty of time to work it out. “Arrow” and the other DC shows aren’t expected to return to the CW until fall.
