Across the Sea is a suspense crime film directed by Cao Baoping, written by Cao Baoping, Wu Pipi and Lao Huang, and starring Zhou Xun and Bo Huang. It is the third work of Cao Baoping's "Burning Heart Series".

The film "The Sea Against the Earth" was adapted from Lao Huang's novel of the same name and started shooting on 20 19. At the beginning of July of the same year, the film started in Dalian, and the second half was filmed abroad. The water play part of the film was filmed in the underwater production center of Oriental Film and Television Industrial Park.

The whole story revolves around fisherman Lao Jin and his daughter Xiao Jinlina, showing a father-daughter relationship full of contradictions and conflicts. The film is "cruel" in the text stage, and director Cao Baoping hopes to bring visual and spiritual impact to the audience through the unique cut-in angle and beautiful text.

Behind the scenes comments:

Before filming, Bo Huang went to the seaside to experience life, lived in a fishing village, boarded a fishing boat and chatted with fishermen. He has deep feelings and understanding for Jiaodong fishermen, and thinks that their rough appearance hides their love for life and heroic and hearty personality. These experiences provided valuable inspiration and material for him to play the role of Lao Jin in the film.

During the filming, Bo Huang and Director Cao Baoping cooperated very well. Cao Baoping is a director with great personality and pursuit. He hopes to show the living conditions and emotional entanglements of fishermen in China through this film. Bo Huang completely trusted the director in the filming and devoted himself to the role, which showed Lao Jin's roughness, tenacity and fatherly love.

As the heroine of the film, the cooperation between Zhou Xun and Bo Huang is also a highlight. Jing Lan, played by Zhou Xun, is a powerful and delicate female character. The conflict between her and Lao Jin runs through the whole story.
