Today, Nintendo hosted a brief direct for The Super Mario Galaxy Movie, which shared the official trailer for the film. In the trailer, we got our first look at two new characters – Rosalina and Bowser Jr. and we got to learn who will be voicing them.

The voice actress for Rosalina is Brie Larson, known for her roles in Captain Marvel and Avengers: Endgame as Carol Danvers. 

The voice actor for Bowser Jr. is Benny Safdie, known for his roles in films such as Uncut Gems and Oppenheimer, as well as many other notable projects. 

These were the only two new voice actors revealed for The Super Mario Galaxy Movie. It’s likely that Yoshi will have no voice actor after there was speculation that he could have one.
