The Headington Shark, a fiberglass sculpture that appeared in an English town in 1986, has become an iconic symbol of protest and art's unexpected meanings. The filmmakers behind the comedy-drama 'Learning to Breathe Under Water' take this concept and transport it across the Irish Sea, creating a film that explores the absurdity of death and the complexities of grief. The film follows a bereaved artist, Peter, who constructs a metal shark on his roof after the death of his wife, impacting his young son, Leo. The film's narrative and tone are a bit uneven, with a mix of amusing lines and moments of whimsy, but it ultimately falls short in its exploration of the characters' struggles. The film's production design and Rory Kinnear's performance are highlights, offering a delicate portrayal of pain and a reminder of the actor's versatility in carrying a lead role. The film's exploration of grief and the absurdity of life's challenges is a thought-provoking journey, but it could have been more impactful with a stronger narrative and tone.
