A few weeks back, Ed Miliband was not seen as "Prime Minister material" by many despite five years of drilling home his credentials as Labour leader.

Now, after a short period of transformation - and with #Milinfandom an electoral phenomenon - the man who wants the keys to No. 10 has starred in his own Hollywood blockbuster.

Well, more of a four-minute electoral advert shot by the acclaimed Paul Greengrass, the man who brought The Bourne Trilogy to the big screen and shot the Oscar-nominated movie Captain Phillips.

With May 7 closing in, and Miliband already pulling out his trump cards of an interview with Russell Brand and a promise to control rent prices - evident attempts to appeal to younger voters - the Labour leader has appeared in a short film portrait that aims to portray Miliband as a man on the side of people "who don't have it easy in this country".

"I feel that the last four-and-a-half years have been leading up to this moment," Miliband says at the start of the video, stating that he has spent his years in opposition formulating policies that are meaningful and there to benefit the majority of the country. "I feel ready to offer myself as Prime Minister."

Miliband speaks movingly about his upbringing and his father, who was attacked by The Daily Mail for his Marxist beliefs. The film shows the Labour leader on the campaign trail, knocking on voters' doors, before cutting to a large segment where he emphasises the need to "rescue the NHS" for "working families."

"I’m not on the side of the richest and most powerful. I’m on the side of the people who don’t have it easy in this country," Miliband says.

Miliband meets voters on the campaign trail.

The Labour leader devotes a large section of the film to the NHS.

Miliband says he is ready to "offer" himself as Prime Minister.

Miliband's full interview with Russell Brand is to be released soon, although a trailer gave the public some insight into how the discussion went.

"Of course people share your outrage about companies that don't pay their taxes and it can be dealt with," Miliband said. "But you've got to have a government that's willing to say 'there's something wrong with this' and we're going to deal with it."
