I came across a line in a movie:
You told me your dad was some fighter. You didn't say he was the most famous fighter to ever live.
This is a line spoken by a girl to a guy, and the guy's father is dead. Shouldn't it be:
You didn't say he was the most famous fighter to have ever lived.
Or
You didn't say he was the most famous fighter who ever lived.
What about
You didn't say he was the most famous fighter who has ever lived.
