As part of his press tour for Guardians of the Galaxy Vol. 3, Will Poulter went “undercover” on social media for a feature in GQ.

Will Poulter saw a tweet from a user who asked why he had dressed up as Sid Phillips, the boy in Toy Story who liked to break his toys.

The user posted a picture of Poulter wearing Sid’s famous black skull shirt and holding a magnifying glass and a Woody doll, along with the question, and asked:

Thought he [Poulter] hated this comparison, so how did this happen in the end? Knowing him he must have done it for a reason.

Then, the “We’re the Millers” star was very honest about why he chose to wear the skull T-shirt for Halloween in 2017.

In response, the 30-year-old actor said:

I did do it in light of some of the comparisons between me and Sid from Toy Story that were going around on the internet.

I work with Anti-Bullying Pro and the Diana Award, I did it during anti-bullying week to raise awareness of that organisation.

So that was that.

Anti-Bullying Pro was established in 2011 as part of the Diana Award. It trains young people in the UK to become anti-bullying ambassadors in their schools.

According to their website, the organization

raises awareness of bullying behaviour and supports schools and young people to tackle it across the UK and beyond.

Will Poulter must have found the comparison funny because he seems to have no problem with online memes.

When Will Poulter posted a picture of his costume, he wrote:

In addition to having a laugh at my expense I wanted to try and raise some attention for a cause I am an ambassador for! @antibullyingpro.

As this month is Bullying Prevention Month in the USA and Antibullying Week in the U.K. is just around the corner, I would really appreciate it if you could please give them a follow before you like or share and help support the cause to make school a safer and happier place for young people.

The actor has starred in movies like The Maze Runner, Son of Rambo, and The Chronicles of Narnia: The Voyage of the Dawn Treader. He has a pretty significant role in the new Guardians of the Galaxy movie.

Guardians of the Galaxy Vol. 3 was released in theaters on May 5.
