Speaking to The AP, Garfield explained that he loved shooting the scenes where Sheen and Field played Peter Parker's Uncle Ben and Aunt May.
"They're incredible, they're just fine actors, and people who live well and live purely and with love, and that's very inspiring 'cause it's rare that you find someone who's not only a fantastic actor but a fantastically beautiful person," he explained.
Garfield went on to reveal that Field and Sheen offered him "more life advice than acting advice".
The actor previously told Digital Spy that he believes Spider-Man's enduring popularity is down to his costume.
"He's the only superhero where you can't see any skin colour. He's covered head-to-toe. Any culture around the world, any child around the world can identify with it and put themselves in that suit," he said.
The Amazing Spider-Man opens in cinemas on July 3.
