In the United States, the song entered at number 86 on the Billboard Hot 100 and elsewhere in the world its success varied, peaking at number one in the Netherlands' Dutch Top 40. The song received positive reviews, with critics noting the music's sound and memorable lyrics. Both the song and its "Thin White Duke" remix were nominated for the 2007 Grammy Awards, the latter of which won in the category of Best Remixed Recording, Non-Classical.
Coldplay had difficulties with the recording sessions for months, as to the sound of the track. They were skeptical in deciding to add "Talk" to the final tracklisting of X&Y. During the recording sessions, which had seen the band scrap huge amounts of material, the song was left out when they sent early versions of the album to its record label, Parlophone. The song, however, made it to the track list, after it was properly mixed.
The music video for "Talk" was helmed by director/photographer Anton Corbijn. Filming of the video took place on 5 and 6 November 2005 at Ealing Studios, London, just before the band began their tour, Twisted Logic. The black-and-white clip invokes a B movie science fiction theme, with imagery ranging from a flying saucer to 3D glasses. The main plot line of the music video features the band as astronauts landing on an alien planet, where they re-activate a dormant robot, who eventually eats them and their spaceship as they are attempting to fly away.
