Zac Efron ‘spotted litter picking in London as part of new Netflix documentary’

Zac Efron was reportedly spotted getting busy litter picking in the capital.

The Baywatch actor was seen by members of the public as he did his bit for the planet on the banks of the River Thames.

A passer-by told the Daily Mirror: “He really mucked in. There was no fanfare over his arrival or anything, he just turned up and got involved.

“Half the volunteers didn’t know who he was, but the kids were really excited.”

According to the publication, the 30-year-old is filming an environmental documentary for Netflix with a focus on food.

Efron was supposedly surrounded by cameras as he mingled with the wildlife on the banks of the river where rubbish typically collects.

The environmentally-conscious actor reportedly also filmed at the London School of Economics and tourist hotspot Carnaby Street.

Standard Online has contacted representatives of Efron for comment.

The High School Musical star is currently anticipating the release of his comedy flick The Beach Bum, expected to hit screens next year.

It also stars Interstellar actor Matthew McConaughey, TAG actress Isla Fisher, True Story’s Jonah Hill and rapper Snoop Dog.
