"Ultimately, you have to not worry about people thinking you should have played him differently. You're the one playing the part so it has to be yours"

In this quote, Ewan McGregor is stressing the importance of remaining real to oneself while playing a character. He is saying that as a star, it is natural to receive criticism or suggestions from others on how a character must be depicted. Nevertheless, eventually, it is the actor's obligation to make the character their own and not stress over what others may think. McGregor is reminding us that as the one playing the part, we have the power to bring our own special interpretation and point of view to the character. It is necessary to trust our own instincts and not be swayed by outside opinions.
