Harrison Ford is still being questioned about whether this really will be his final outing donning the battered hat of renowned explorer Indiana Jones. When an artist announces a "last" project, there is frequently speculation that it won't be.
But in his response to BBC News, the actor is clear-cut.
He declares, "This is my last movie.". And I always had big plans for this last movie. ".
One could argue that considering Ford is now 80 years old, the film Indiana Jones and the Dial of Destiny, the first for the franchise since 2008's Indiana Jones and the Kingdom of the Crystal Skull, wasn't even required to wrap up the series.
Although acknowledging the passage of time, the actor claims he wanted to give this adored character "an emotional ending.".
I wanted to see that developed into a complex story because, as he says, "we've been making these films for 40 years, we can't deny the effect of age on the character.".
While engaging in action stunts with his goddaughter Helena, who is played by Phoebe Waller-Bridge, as they pursue an ancient dial that has the power to change the course of history, the movie plays up the character's advanced age.
The movie is filled with inside jokes about the protagonist as well as scenes with the Nazis, who are played by Mads Mikkelsen, a former Bond villain and one of Indiana Jones' greatest enemies.
Ford, however, is adamant that he won't give in: "I wasn't so much interested in doing the same thing over and over again, I wanted to have an emotional ending to this character.
"I just wanted to make sure that they would be happy and satisfied with the final iteration. I'm so grateful for the audience that we've had. ".
That's not a guarantee, though, as the movie's critics gave its world premiere at the Cannes Film Festival mixed reviews. The movie was "a depressing reminder of how much livelier his past adventures were," according to the BBC review at the time.
Steven Spielberg is still an executive producer, but it's also the first movie in the series that he hasn't directed.
On the American review aggregation website Rotten Tomatoes, Dial of Destiny was once rated at only 52%, but it has since improved.
However, the element of nostalgia may still be a strong draw for viewers. Mikkelsen, who is among those who can recall the 1980s film trilogy starring Indiana Jones, including Raiders of the Lost Ark, Indiana Jones and the Temple of Doom, and Indiana Jones and the Last Crusade, claims that "anyone I know would have killed me if I turned it down.
When I was 15 years old, I first saw it. And it was a great source of inspiration for me as an actor, as well as for many of my colleagues and directors. ".
In this film, Harrison Ford, a modern actor who has undergone technological changes, portrays Indiana Jones in all his glory in a lengthy flashback scene.
According to Ford, the pictures "exactly depict how I looked 35 years ago. Because they are real images, they are not unsettling or Photoshopped. ".
In Martin Scorsese's The Irishman, Robert De Niro's character was also digitally altered to change his age in the mafia movie, and as Dial of Destiny director James Mangold explains, the technology is still developing.
According to him, "Steven Spielberg shot four Indiana Jones movies with Harrison, three of them were in the time period that the opening sequence is set in.
He therefore had a collection of Harrison's face, every expression, and every lighting technique. Harrison is also only a few pounds heavier than he was when he was 35 years old. Since the man's bones haven't changed in the least, computer mapping makes it simple to put that young, fleshy visage on him. .
The performance is being led by him. With the knowledge that he is portraying a younger version of himself, it is more than just motion capture. ".
The character of Helena, referred to in the Guardian's review as "a naughty Enid Blyton heroine," was played by Emmy-winning Fleabag actress and writer Waller-Bridge.
She claims that during a punching scene, Ford instructed her to "act like you're hammered.".
I was anticipating getting punched in the scene, so I was extremely tense. Just act like you're hammered, he said as he approached her. I was regularly given that kind of mature advice, she quips.
"However, just the stunts were the best time of my life. They used to make me unhappy, but now they make me happy, being thrown off things, tripping over things, or even just being hung from a ceiling. It never gets boring. " .
I had no idea she would be so capable and fearless, says Ford of her action performance, which is "terrific.".
But if its creators want to continue the franchise, Waller-Bridge reportedly disqualified herself from taking Harrison Ford's place. When asked who should take over as Indiana Jones, Ford joked to reporters at the US premiere, "Jennifer Lopez would be fantastic.".
But the actor isn't going away. He will continue to appear in two series: Shrinking and the western 1923 with Helen Mirren, in which he portrays a cynical therapist.
The actor reiterates that the life chapter involving Indiana Jones is now complete, saying: "I just feel a sense of completion. " .
In the UK, Indiana Jones and the Dial of Destiny will be available on Wednesday.
