Armed with his sister�s dress-up clothes and a few homemade props and improvisations, the adventurous Bassendean resident has put on wigs, dresses, cosmetics and prosthetics to mirror about 60 pop-culture characters.
The process is a prelude to the film fanatic cutting off his long locks to raise money for the Cancer Council.
People nominate a famous character for him to imitate on his Facebook page for a donation before he reaches for a pair of scissors.
The task has gained traction, with more than 380 likes and more than $2200 raised so far, more than his $1500 goal.
�One of my friends did it, but he just cut his hair and I wanted to do something different,� Jack said.
�I think I will miss my hair when it is cut but it will grow back.�
Jack�s mum Suzannah said Jack was touched by the experiences of other people who faced cancer.
�We are very fortunate, no one in our family has had cancer, but people we do know have it or someone in their family does and I think that affected Jack,� she said.
Ms Churchman said she jumped at the chance to help Jack in his fundraiser by even recreating scenes that he was not old enough to see for himself.
�He just loves movies,� she said.
�At one point, we used his dad�s trousers as a jacket because it was the right colour.
�We used flour and water to make a nose for Voldemort.�
While he may not fully understand the horror behind Jack Nicholson�s �here�s Johnny� moment in The Shining, or Sigourney Weaver�s gun toting Ripley from Aliens, Jack nevertheless adopted their likeness.
He said his favourite re-creation was, however, from the age appropriate Big Hero 6.
