This is the moment a furious Megatron dresses down a “stupid” man who gave the Decepticon leader the middle finger and calls him a “dirty human being” at Beijing’s newly-opened Universal theme park.

The angry Transformer was filmed losing his rag at Universal Beijing Resort in the Chinese capital Beijing on Tuesday.

In the footage, a cheeky young visitor is seen approaching Megatron and showing him the middle finger, apparently to impress pals taking snaps nearby.

However, in the character’s distinctive voice, Megatron shoots back at the rude tourist: “That is so impolite. Didn’t your parents teach you anything?

“Stupid man. Dirty human being. Go back, I don’t want to take a picture with you.”

After opening on 20th September, Universal Beijing Resort officials said there are currently no rules in place to prevent visitors from carrying out such gestures against film characters, but park employees will politely ask them to refrain if they catch them in the act.

The park also explained that an employee used the phrase “dirty human being” to quote the character in the films and it was not meant to be derogatory to the tourist, adding that the voice is controlled by staff backstage.

Universal Beijing Resort is the film studio’s largest park and fifth around the world.

It is also considered a first for the Chinese capital Beijing, which until now could not boast a big-brand theme park like Hong Kong and Shanghai, both home to a Disneyland.
