She-HuLK is rumored to appear in the upcoming Captain America 4 movie.
Thus, it is reported that She-Hulk's first MCU movie will be released in the upcoming movie 'Captain America: New World Oder'.
As usual, Tatiana Maslany will play She-Hulk and this is reported by KC Walsh, an Insider.
This is a part of a related note.
She-Hulk: Attorney At Law will end with TheLeader getting Jen's blood (will be one of his underlings). This will be the basis of other Hulk's in the MCU who will be made through Jen's blood. Captain America: New World Order will introduce these other new Hulks made by The Leader."
But there is no official report about this yet and it is believed that this is very likely to happen.
