If you not impersonating Morgan Freeman, and there is no history or framing to make that connection, he is unlikely to sue you, or win a lawsuit.

Courts are quite aware that similar things can come from divergent sources.

Even copyright law fails to protect commonality between works that would be illegal if actually copied, but were arrived at legitimately and credibly independently.

Not saying someone shouldn't use common sense to avoid problems. Don't do Morgan Freeman impersonations comedically, then voice overs of movies.
