Sharon Stone, Christoph Waltz, and Kevin Hart

This one is quite old – Sharon Stone will be yet another Hollywood star to join the ever-expanding cast of the MCU. The actress herself teased this possibility when she said that she’ll have a tiny role in an upcoming Marvel flick. Obviously, she must have been talking about the Ant-Man and the Wasp sequel, in which she’ll most likely portray the first Wasp, who got lost between dimensions.

As far as Kevin Hart is concerned, he is also rumored to appear in the Ant-Man sequel. But I wouldn’t bet on it. Even if his movies bring money and even if he is an A-lister, Ant-Man already has the awesome Michael Peña playing the comedic sidekick.

Christoph Waltz is yet another big name rumored to be added to the cast of Ant-Man and the Wasp. However, nothing has been confirmed. And, quite frankly, Waltz has already portrayed his share of awesome villains on the big screen. So maybe he should pass on this opportunity (especially since Marvel isn’t exactly known for its great villains).
