Director and producer Paul Greer, whose first stop-motion film took six months in 2013, has used Hot-Wheels toy cars to create incredible stop-motion miniature chase scenes.

Stop-motion films are created by taking a photo of a scene before changing the position of the models to some degree and snapping another photo and creating a sense of movement.

Paul created a piece of unique camera equipment and used an iPhone to record the sequences in his debut movie. 

“I was walking through a Waitrose, and I saw some toy cars, so I thought, I should do something with this.”

Four friends helped the filmmaker and worked on the project for up to six hours daily.

The process proved grueling and only resulted in footage between five and 10 seconds. Nitro Warriors was born after more than 1,000 hours of work and showed great success.

French video-sharing technology platform DailyMotion contacted Paul to create a sequel before Hot Wheels asked him to film an advertisement for their toys.

Till now, Paul has created over 10 films and opened a stop motion studio called Vanguard Pictures.

"I take breaks from my regular career to work on this and work solely on this,” he said, adding, “It’s so all-encompassing that you need to dedicate yourself to it completely."

"The most overwhelming thing was when Hot-Wheels came and said, 'we have a lot of money, and we want you to promote our entire line of toys.'"

Greer doesn’t know how or why he became so interested, he said. "It just sort of came about."

"For me, the biggest reward is that there are people out there enjoying what I make."
