Here's what we can find:
* IMDb: His IMDb page lists him as "Danny Martelli" and credits him in 2008's "The Dark Knight," as well as some TV shows including "Entourage," "The Closer," and "Cold Case." It's likely he was involved in stunt work on these projects, rather than acting roles.
* Film Database: His Film Database profile lists a few more film and TV credits. Again, these are mostly stunt work, including "Transformers," "Iron Man," and "CSI: Miami."
To find more specific information, you would need to:
* Contact Danny Martelli directly: If you can find his contact information, you could reach out to him for more details about his work.
* Contact production companies: If you know which companies produced the projects you're interested in, you could try contacting their archives or stunt departments.
* Use specialized resources: Some online resources are dedicated to stunt professionals, which might have more detailed information.
Keep in mind that due to the nature of stunt work, it's often difficult to find a lot of detailed information about individual performers.
