Films and Filming Magazine released in the UK in March 1987. An interesting interview with Christopher Reeve.
“Part I, I was really lucky to get the job. Part II, I was gaining experience. Part III, a bit of disillusionment, and Part IV hopefully inspiration, Realisation, fulfilment.”
“I don’t want to outlive my enthusiasm for Superman. Getting back to predictions here. I just don’t want to be in a position where I have to be dragged to the set. I want to feel motivated as I have done on this one. This may be it. I may end up feeling that I’ve done everything I can do with this part, in which case I’ll just have to see what awaits me without the Superman security blanket to fall back on anymore.”
