Krishnan Guru-Murthy vs. Robert Downey Jr. (2015)

Krishnan Guru-Murthy's 2015 interview with Robert Downey Jr. is the most confrontational press junket on this list, driven by questions about drug history and prison time during an Avengers: Age of Ultron promotion. The exchange escalated until Downey Jr. removed his microphone and walked out, with the clip amassing over 8 million YouTube views. This outburst outperforms #6 Crispin Glover's Letterman incident in sheer awkward tension, as no host here triggered a premature exit faster.
