The 34-year-old star - who is best known for his role as Peter Parker in the `Spider-Man` films - believes he must have a familiar face because fans always get his name wrong, but he doesn`t mind because he just carries on the pretence.
He said: "I`m been mistaken for so many different actors, it`s just wild. I`ve gotten Jake Gyllenhaal a few times like, `Loved you in `Brokeback Mountain`. I`ve had that. I can`t remember all of them, but Elijah Wood is another.
"When people ask me for my autograph and say, `Oh you were so great in such and such,` which I wasn`t in, I usually just sign the other actor`s name and say, `Thank you very much.? "
Tobey - who stars with Jake in new movie `Brothers` - also claims he is so busy he`s even started organising his life on paper and has been writing lots of lists so he can remember everything he`s done.
The actor - who has two children, three-year-old daughter Ruby and seven-month-old son Otis, with his wife, jewellery designer Jennifer Meyer - told Parade.com: "It`s just all a time issue. Recently, I`ve been putting my life down on paper, listing what I spend my time doing because I`m trying to edit some things out in order to make more time for the things that are important to me.
"It`s kind of a process of self-reflection on how I`m living and spending time with my wife and children, which is a number one priority. But, I love my work as well, so that`s very important too."
