Kronsteen – McAdams, 1963

Continuing my theme of fictional chess scenes based on real chess games.

In the famous chess scene at the beginning of the Bond movie "From Russia With Love" we see Kronsteen of SPECTRE playing the Canadian McAdams. The score is 11½–11½. The scene is based on Spassky-Bronstein from the 1960 USSR Championship.

Spassky-Bronstein
1.e4 e5 2.f4 exf4 3.Nf3 d5 4.exd5 Bd6 5.Nc3 Ne7 6.d4 0-0 7.Bd3 Nd7 8.0-0 h6 9.Ne4 Nxd5 10.c4 Ne3 11.Bxe3 fxe3 12.c5 Be7 13.Bc2 Re8 14.Qd3 e2 15.Nd6 Nf8 16.Nxf7 exf1Q+ 17.Rxf1 Bf5 18.Qxf5 Qd7 19.Qf4 Bf6 20.N3e5 Qe7 21.Bb3 Bxe5

This is the starting position in the movie, except that the two White pawns on d4 and c5 were removed. Both the real and movie games continued...

22.Nxe5+ Kh7 23.Qe4+ (1-0)

However, what's odd is that in the original game, 22....Kh7 was not a blunder as Black had no defense. But in the movie, McAdams could have defended with 22....Ne6, which would not have worked in the position facing Bronstein.

So my question is WHY would the movie producers change the board position? Were they TRYING to make the point that Kronsteen could have been held off with calm defense, or am I giving them too much credit?
