If you are treating "Citizen Kane-like" as an adjective for a following word, I would write it as I did in the beginning of this sentence. I do not believe there should be a hyphen between "Citizen" and "Kane" only because the words work together to form a title, "Citizen Kane." Essentially, I think "Citizen Kane" should be treated as if it were one word. I also italicized "Citizen Kane" because it is a title.
Example: His Citizen Kane-like behavior was intriguing.
I hope this helps!
