As the release date of Harry Potter And the Deathly Hallows: Part II draws nearer, the all-grown-up stars have opened up about the difficulties of filming the last of eight films.
Rupert Grint said kissing co-star Emma Watson in the new film was "really weird" because they had known each other for so long.
The actor, who plays Ron Weasley, said neither he nor Emma - who plays Hermione Granger - were looking forward to filming the scene in Deathly Hallows.
He told Daybreak: "It sounds crazy because of course she's lovely and I'm sure loads of guys are just really jealous, but it just really felt weird for some reason.
"Just because I've known her for so long - since she was like nine years old.
"I remember seeing her face getting closer and closer as I was leaning in, and I thought 'What are we doing, this is just really weird?'"
Grint also confessed all three of the film's main stars burst into tears as they filmed the final scenes in the long-running series.
He said: "We kind of knew it was coming and building up to that final week, and yes, it was just like ten years - my whole childhood - came down to this tiny little scene and that was it.
"It was really sad, we all cried. It was kind of seeing Dan and then Emma cry that triggered me, and it was kind of this weird mix of emotions really - it's hard to describe."
What Daniel Radcliffe, who plays Harry, found 'tricky' about the new film was reaching new levels of depth in his character:
"Finding the emotional depth that you have to find for Harry in this film was tricky - I think I've got there to an extent, particularly at the end."
In this film, Dan's character faces more danger than ever before, and the self-critical actor, 21, said he struggled to live up to the standards he set for himself during filming.
"I'm never going to be completely happy with my performance," he explained.
"But I enjoyed it as much as I could while I was watching it. I was more pleased than I thought I would be."
The last Harry Potter film looks set to make its UK debut in traditional fashion - to the accompaniment of thunder and rain.
The stars of the films have got used to squelching up the red carpet after being caught in downpours before premieres in London's Leicester Square.
Tom Felton (right), who plays Draco Malfoy, said he expects Thursday's premiere to live up to "tradition".
He added: "I can imagine there will be a few showers and rain on the night. It wouldn't be right if it wasn't."
