Gronkowski almost spiked a shark in 'Sharknado' movie

There have been plenty of cameos in the "Sharknado" franchise, but there was one name at the top of the list that the filmmakers just couldn't make it happen with: Rob Gronkowski.

While there was interest on both sides in having the New England Patriots tight end appear in a "Sharknado" movie, their schedules never matched up, according to Chris Regina, former head of Syfy's original films division.

"The one cameo I regret was that we never got Rob Gronkowski, who by the way was like the longest one we kept chasing over and over again," Regina told Jordan Zakarin of Syfy Wire. "He wanted to be in 'Sharknado,' and after so many of them, we could just never get the schedule together for him. We always wanted him spiking a shark."

Mark Cuban, Tony Hawk, Jerry Springer, David Hasselhoff, and George R.R. Martin are just some of the stars who have made a cameo in the "Sharknado" movies.

Gronkowski's acting credits include "Entourage," "American Violence," and the upcoming movie "Boss Level."
