I'm not sure specifically who 'Mike Marcum' is without more context. There could be many people with that name. It could be an ordinary individual with a personal story known only to his family and friends, or perhaps someone with a story within a particular community, job field, or local area.
Sorry, I don't have enough information to tell you about Mike Marcum's true story. It could be that he has a story related to his education, like being the first in his family to graduate from college and how that changed his life's trajectory.
I'm not sure. It depends on where the story originated and what's been said about it. Sometimes stories labeled as 'true' have elements of fiction mixed in.
Mike is not based on a true story. It's likely the product of the author's imagination or a combination of various fictional elements to create an engaging narrative.
It's not a true story. 'Like Mike' is a work of fiction that was written to appeal to a wide audience and provide an enjoyable cinematic experience. The events and characters are made up.
