Some of the stars of the Fox musical series “Glee” have spilled insider info about this Sunday’s Super Bowl episode, using terms such as “epic” and “ginormous” to describe the hotly anticipated production, SheKnows Entertainment reported.

Fans of the show can expect stunts, pyrotechnics and a Sue meltdown the likes of which has yet to be seen, according to various cast members.

“We do a lot of stunts in our big dance numbers,” said cast member Matthew Morrison. "We had a lot of BMX riders, doing all these crazy flips. There was a lot of pyrotechnics."

Jane Lynch, who plays the volatile Sue, added: Sue tries to top herself. She’s bored with her routines and tries to shoot Brittany out of a human cannon. Figgins won’t let her, because of insurance and liability issues, so she throws a hissy fit. It’s operatic, like you can hear (Richard) Wagner in the background as she’s tearing things apart."

Series star Lea Michele had her own take on the episode. "It’s very back-to-basics ‘Glee,’ but has some grand moments,” she said. “It reminds me of episode four, where they did ‘Single Ladies.’"

The episode airs after the Super Bowl this Sunday, Feb. 6.
