Keira Knightley and Mark Ruffalo star in Begin Again

The British actress Keira Knightley, known for playing tragic heroines in period dramas, strays into new territory with her first major singing role in Begin Again, a feel-good film about the music industry and starting over.

The film was written and directed by the Irishman John Carney, whose 2006 indie musical Once nabbed the best original song Oscar for Falling Slowly. It was also adapted into a Broadway show and won eight Tony awards, including Best Musical.

Like its predecessor, Begin Again is laced with music. Much of it is sung by Knightley, along with the Maroon 5 frontman Adam Levine, who makes his film debut.

"The whole thing was out of my comfort zone. I am not a singer. I didn't know how to do that," says Knightley, a Best Actress Oscar nominee in 2006 for her role in Pride & Prejudice.

“A lot of the film was improvised and I had never done that before. I’d say that those were two major things to be grappling with,” adds the 29-year-old actress, who took voice lessons to prepare for the film.

She plays Gretta, a British songwriter and reluctant singer who arrives in New York with her boyfriend Dave, played by Levine, just as he is about to hit the big time.

Fame clouds his judgement and he strays, leaving a bereft Gretta on the verge of returning home when she is discovered by Dan, a chain-smoking, down-and-out record producer played by the Oscar-nominee Mark Ruffalo.

“Essentially, what it is about is people falling down in life and trying to pick themselves back up, whether that is romantically or whatever,” says Knightley.

Dan persuades Gretta to record her songs live on the streets of New York for a CD to revive his own non-existent career. Along the way, the two strike up an unusual ­friendship.

“I like the meditation on the character’s journey back to his creative self from this material world, coupled with a mid-life crisis and a marriage that is going through a transition,” Ruffalo says of the role and his character’s transformation. “There is just a lot of fertile ground.”

Catherine Keener (Capote) plays Dan's estranged wife; the Oscar-nominee Hailee Steinfeld (True Grit) is his rebellious daughter; and the 2012 best-actor Tony winner James Corden (Gavin & Stacey) is Gretta's struggling musician friend Steve.

The Grammy-winning rapper CeeLo Green and Yasiin Bey, formerly known as the hip-hop artist Mos Def, play Dan’s music-biz ­colleagues.

Ruffalo, whose career started in the theatre, would be happy if, like Once, Carney's new film was adapted for the stage.

“I think this could be an easy move,” he says. “So much of the work is already done.”

What is blockchain?

Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.

The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.

Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.

However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.

Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.
