Evidence that Matthew Dellavedova is The Feral Kid from Mad Max 2: The Road Warrior:
1. They are both from Australia
2. They look sorta the same
3. They’re both scrappy as get-all
4. I’ve never seen Matthew Dellavedova and The Feral Kid from Mad Max 2: The Road Warrior in the same room
Evidence that Matthew Dellavedova is not The Feral Kid from Mad Max 2: The Road Warrior:
1. The Feral Kid is a fictional character
2. The Feral Kid was played by Emil Minty, who is not Matthew Dellavedova
3. Mad Max 2: The Road Warrior was released in 1981, nine years before Matthew Dellavedova was born
Conclusion: Inconclusive. Until I see them in the same room, jury is still out on this one.
