The Icelandic composer, who was behind the Golden Globe-winning music in Steven Hawking biopic The Theory of Everything which starred Eddie Redmayne, was found dead in Berlin.
A cause of death is yet to be confirmed.
His representatives, Redbird Music Management, issued a statement on Facebook that read: “It is with profound sadness that we confirm the passing of our dear friend Johann.
“We have lost one of the most talented and brilliant people who we had the privilege of knowing and working with. May his music continue to inspire us.”
“We are deeply saddened by the sudden loss of our client and dear friend Jóhann Jóhannsson, whose great talent, humility and kindness enriched our lives immeasurably”
Meanwhile a statement from his agency Gorfaine-Schwartz read: “We are deeply saddened by the sudden loss of our client and dear friend Jóhann Jóhannsson, whose great talent, humility and kindness enriched our lives immeasurably.
“His music has inspired many new generations of filmmakers and composers. He will be so greatly missed by his Gorfaine/Schwartz family as well as the entire film music community.”
Known for blending electronic with classical orchestrations, Johannsson was nominated for both an Oscar and BAFTA for his soundtrack to 2015 film Sicario and 2016 sci-fi flick Arrival.
Johann was also a very accomplished solo musician, with his most recent album Orphee being released in 2016.
He is survived by his parents, three sisters and daughter.
TV and radio host Edith Bowman led tributes for the star on Twitter.
She wrote: “This is just the saddest of news. RIP Johann, your vision and creations will eternally inspire and influence me. Love and thoughts to all family and friends.”
Experimental producer Flying Lotus tweeted: “Johann Johansson has been such an influence, especially lately. I’m in disbelief. The stuff he did for Panos Cosmatos’ Mandy is incredible.”
While film director Aaron Moorhead added: “We just lost Johann Johannsson, one of the best composers in the world. Died just as he was getting started. Throw on IBM 1401 all day, The Sun’s Gone Dim is like he wrote his own requiem. This is devastating.”
