Rege-Jean Page and Justice Smith lark about at Dungeons & Dragons afterparty in London

Rege-Jean Page and Justice Smith looked in high spirits as they attended the Dungeons & Dragons: Honor Among Thieves after party on Thursday night.

The actors, who appear together in the upcoming American heist-fantasy comedy-drama, laughed and joked after the star-studded premiere at Cineworld Leicester Square in London.

Hugging her co-star, Rege, 34, put an arm around Justice’s shoulder and the pair shared a giggle as they frolicked in The Crypt.

Dressed in a baby blue suit, Justice, 27, reciprocated the gesture and gently held onto Rege’s suit cuff.

In one photograph, Justice covered her face with her palm after sharing a quiet exchange with the former Bridgerton star.

Party: The actors, who appear together in the upcoming American heist-fantasy comedy-drama, laughed and joked after the star-studded premiere at Cineworld Leicester Square.

They also posed for snapshots with I Am Not Okay With This and Sophia Lillis, 21, of Sharp Objects, who takes on the role of tiefling druid Doric in the upcoming film.

Dungeons & Dragons: Honor Among Thieves will hit theaters nationwide on March 31.

Chris Pine takes on the lead role of Edgin Darvis in the heist comedy, a father trying to care for his daughter Kira, played by 14-year-old Chloe Coleman.

The 42-year-old Star Trek actor described the process of creating the film as “joyful, creative and imaginative”.

Meanwhile, Rege-Jean plays Xenk Yendar, a slowly aging paladin, and Justice plays Simon Aumar, a wild magic warlock.

Hugh Grant, 62, also joins the cast and plays con man Forge Fitzwilliam, a former member of Edgin’s gang.

Earlier in the evening, Rege-Jean revealed that her first game of D&D was with her co-stars and that they all sat down to play before filming began.

Speaking to PA, he said: “It’s a natural place for the actors to hang out, a great improv game, but with magic and dragons.”

Lively: Both parties seemed to be having a great time in each other’s company.

“Just think of it as the wildest, most magical thing you can do, and then you pass it on to the player next to you.

“Gamers (like) Chris Pine are so sharp, so resourceful, it gets even wilder than magic.”
