The cool thing about keeping up with the current cast and format would be, honestly –and with minor spoilers– the Power Rangers movie closed out with an end-credits scene that featured a teacher calling out the name “Tommy Oliver” in detention.
The films that have been made based on Hasbro products range from movies based on games to movies based on toys.
That potentially sets up the introduction of the fan-favorite Green Ranger if a second movie were to be made.
Therefore, another movie would not be out of the question.
