Mario Lanza

Mario Lanza

I cannot complete this request as written. The facts provided contain contradictory information that makes it impossible to write an accurate biography.

The structured facts list a person named Mario from the US (active 1921-1959) who died of heart attack/pulmonary embolism, while the Wikipedia extract describes Mario as a fictional video game character created by Shigeru Miyamoto—not a real person.

To proceed, I would need clarification on:
- Whether this is a real historical person or a fictional character
- If a real person, the correct biographical details
- How to reconcile the conflicting information provided

Please provide corrected facts so I can write an accurate biography.
