Upon arriving they pose as a married couple and meet René Mathis, their contact in Montenegro. Each poker player has their money in a Swiss bank in Escrow while they play, and each one has a password to keep the money secured. On the first hand, 007 loses a chunk of cash to figure out how Le Chiffre bluffs (his physical "tell" involves him placing his left hand near his wounded eye); however, Vesper is not at all impressed, thinking Bond is inept. Bond places a tracking device in Le Chiffre's inhaler and takes Vesper back to their room. In Madagascar, Bond is working with another MI6 agent, Carter, monitoring a terrorist, Mollaka, who is gambling on a fight between a cobra and a mongoose. Carter, who is inexperienced, is exposed after Mollaka gets a cell phone call and the terrorist bolts from the scene. Bond chases Mollaka, who is an experienced "free runner", who leads Bond through a construction site, onto several cranes and finally to the Nambutu embassy where he seeks asylum. The mainland Chinese cut of the film also trims the torture scene and the stairway fight, as well as a shot of Bond cleaning his wound at the hotel, and a boat scene. A three-disc edition of Casino Royale on DVD was released in the United Kingdom on 31 October 2008, coinciding with the cinema release of the sequel, Quantum of Solace (the following week in the United States). As well as features present from the 2007 release, the collector's edition contains an audio commentary, deleted scenes, featurettes and a storyboard-to-film comparison. A two-disc Blu-ray version also followed in late 2008, featuring additional supplementary materials, enhanced interactivity through BD-Live, and the previous version's 5.1 PCM soundtrack was replaced with a similar 5.1 Dolby TrueHD soundtrack. The first scenes shot were ones involving a Madagascar building site, shot in the Bahamas on the site of a derelict hotel with which Michael G. Wilson had become acquainted in 1977 during the filming of The Spy Who Loved Me.
