Slumdog Millionaire actor Dev Patel kept a low-key at the movie’s official party.
The 18-year-old refrained from burning himself out to preserve the energy for the big Oscar night.
“It’s OK to be thrilled but best not be too extravagant this time. Winning is enough,” the Sun quoted him as saying.
A source added: “He’s young and it’s important he doesn’t do too much.”
The movie scooped eight Oscars, including best film and director, after having dominated Golden Globes and BAFTA previously.
