Please answer a question about the following article about Spectre (2015 film):

Christoph Waltz was cast in the role of Franz Oberhauser, though he refused to comment on the nature of the part. It was later revealed with the film's release that he is Ernst Stavro Blofeld. Dave Bautista was cast as Mr. Hinx after producers sought an actor with a background in contact sports. After casting Bérénice Lim Marlohe, a relative newcomer, as Sévérine in Skyfall, Mendes consciously sought out a more experienced actor for the role of Madeleine Swann, ultimately casting Léa Seydoux in the role. Monica Bellucci joined the cast as Lucia Sciarra, becoming, at the age of fifty, the oldest actress to be cast as a Bond girl. In a separate interview with Danish website Euroman, Jesper Christensen revealed he would be reprising his role as Mr. White from Casino Royale and Quantum of Solace. Christensen's character was reportedly killed off in a scene intended to be used as an epilogue to Quantum of Solace, before it was removed from the final cut of the film, enabling his return in Spectre.

In what movie was Mr. White originally supposed to die?
Quantum of Solace
