I believe EON had him as next name on the list if Brosnan hadn't been available for GoldenEye.
So, how would the fourth doctors regeneration go ITTL? Would he regenerate in the fifth story of Season 17? Would he regenerate off screen? Would he regenerate at the start of Season 18No, no and no. The last story of Season 17 is a victim of the strike and it's a FAR bigger headache for the production team than Shada was. They've had to abandon the last Fourth Doctor story. Uh-oh.
