India, Nov. 17 -- Hrithik Roshan's recent Super 30, where he played the role of mathematician Anand Kumar from Bihar, is very close to his heart and has left a deep impact on him.

The actor has now taken this love to another level, and has got a customised wallpaper of numbers, mathematical equations and formulae, displayed in his vanity van.

"Hrithik Roshan adopted Anand Kumar's lifestyle while he was shooting for Super 30. He used to speak in that dialect with his sons [Hrehaan and Hridhaan], driver, staff and everybody around for three continuous months. The character did not leave him easily," a source shared.

Reportedly, Hrithik himself does not want to leave that character and is making sure he keeps a part of it in his life.
