Michael Caine has been looking back, and on the whole he likes the view.
The 85-year-old star of Alfie, Get Carter and The Dark Knight - among many, many others - reminisces fondly in Blowing the Bloody Doors Off - the title a nod to 1969 heist caper The Italian Job.
Being published today in the United States by Hachette, it's part memoir, part advice manual for aspiring actors and others nursing a dream of success.
Most of the advice is resolutely old-fashioned. Learn your lines. Work hard. Be nice to people. And be lucky. Caine knows he has been extremely fortunate.
"The luck I've had, you couldn't make it up," Caine said during an interview in his riverside London apartment, with a panoramic views of the Thames. "I mean, even once I was a success, I made a lot of flop movies. But I only made three at a time before I had a hit."
In print and in person, Caine describes his success as sequence of lucky breaks.
His first big movie break, as a British Army officer in Zulu in 1964, was followed by a role as a world-weary spy in The Ipcress File. Then came his breakthrough as a callous man-about-town in Alfie. That film made blond, bespectacled Caine a symbol of Swinging London, brought him American fame and earned him the first of six Academy Award nominations.
He went on to win two Oscars - for Hannah and Her Sisters and The Cider House Rules.
Later came a stint as butler and mentor Alfred in three Batman movies directed by Christopher Nolan. Along the way, he became an icon, his glasses and Cockney accent spawning a thousand imitators.
Caine says his optimistic outlook is rooted in his hardscrabble early years. Born Maurice Micklewhite into a working-class London family, he was a child during the London Blitz then went as a teenage conscript to fight in the Korean War.
"I have found it pretty easy to be happy since then," he notes in the book.
When he returned to London and a dead-end job in a butter factory, Caine resolved to be an actor, although he had little idea how to go about it.
"I was nobody from nowhere who knew nothing about anything," he said.
His drive to succeed came from "desperation".
"My father was an extremely clever, intelligent man but completely uneducated and a complete waste of a brain - and that's what was happening to me."
Answering an ad led to small parts in a provincial repertory company. Then came work on the London stage, television parts, movie roles and global stardom. If he has a secret, he says, it's that he kept going when others gave up. "If someone rejected me, I never worried about it," he said. "I tried again, because my only alternative was working back in the butter factory.
"But also, timing played a massive part."
Caine was starting out just as a new generation of writers was emerging - playwrights like John Osborne and Harold Pinter, telling stories about working-class life. "Suddenly every working-class boy who was going to work said: 'Sod this. I'm going to do something I want to do and do it my way'," he recalled.
The 60s made Caine a star, and he wasn't alone. Suddenly, he writes in the book, "everybody I knew seemed to become a household name".
Caine enjoyed fame, when it came, but also worked extremely hard, at one point making 12 films in four years.
The result is a resume of more than 100 features, of varying quality. Caine is cheerful about the low points, films like schlocky shark sequel Jaws: The Revenge or The Swarm, a disaster movie in both senses of the word where Caine and his co-stars learned another lesson: Never work with bees. "I learned from them - also earned from them," he said of his critical duds. "I got the same money for the flops as I did from the successes." When leading-man parts dried up, Caine retired - briefly. The past 20 years have brought some of the most rewarding parts of his career, including his six films with Nolan, whom Caine calls "a brilliant director ... the new David Lean".
These days, Caine is contentedly unretired, balancing work and time with his family: Shakira, his wife of 45 years; his two daughters; and his three grandchildren, with whom he is "besotted."
Of his recent films, he's proudest of Italian director Paolo Sorrentino's Youth, in which he played an ageing orchestra conductor. "I just take little character parts and have a bit of fun."
