The London born and raised star was just a struggling actor and musician before his role in "Harry Potter and the Goblet of Fire," an installment of one of the most successful movie franchises in film history.
Pattinson started out his career by playing the role of Cedric Diggory in the movie, and although it was not a major role and the character was killed off in the film, it catapulted Robert into new fame territory.
"When Harry Potter came along, it was a huge step and a massive event in my life!" the Twilight actor said to Sheknows.com.
When Robert was 17-year-old, he was working in South Africa and he met the casting agent for the Potter films and it was then that he auditioned for the part.

"I didn't know how I would be interpreted, so I went into Harry Potter determined to be a real actor and kind of didn't speak to anyone for awhile. I didn't notice the transition to being accepted, but they are all really nice people. It seems like it should have been daunting, but it wasn't. We did a bonding week where we made fools of ourselves, doing lots of improvising. I paired up with Rupert a lot," he said.
Filming the movie was a bit challenging for the neophyte actor as there were complicated sets and stunts he had never been exposed to. Robert declared that he found his role challenging as Cedric Diggory was often involved in the most action packed parts of the film.
"It was a very physical part. The stuff in the maze, which was done in the beginning, was done on all huge action sets. The hedges were huge and hydraulically operated. I got hit by stuff and was pulled by ropes, and Dan (Radcliffe) and I were running around punching each other, so it was kind of vicious."
Since then, Robert has appeared on all of the "Twilight Saga" films as the heroic vampire Edward Cullen and has an incredible following of adoring fans. The actor has begun his attempt of establishing himself as a serious actor by starring in films like "Remember Me" and "Water for Elephants."
"Harry Potter and The Globet of Fire" was exactly the push the actor needed to create a fan base as well as garner the experience necessary to succeed in the film industry and is now one of Hollywood’s leading men.
