Both films are available to rent and buy on Amazon Prime Video.
There are also two non-official James Bond films available to watch - 1967's Casino Royale starring David Niven, and 1983's Never Say Never Again which saw Sean Connery reprise his role as the double agent. As such, the order in which to watch the James Bond reboot films is as follows: Casino Royale (2006) Quantum of Solace. GoldenEye (1995) - after pre-titles sequence Craig’s era - and presumably timeline - as Bond ends with No Time To Die.
GoldenEye (1995) - pre-titles sequence only.
