There is an anecdote about STAR TREK - The Motion Picture, no idea whether there is any truth to it: Harlan Ellison sits with the executives of Paramount discussing possible story ideas for STTMP. The top suit calls for something BIG, Ellison pitches this: '...and after crossing the universe the Enterprise comes to this gigantic wall, there's no going around it so they try to break through and that wall starts coming apart and behind it is the face of God.'
...(silence for a few seconds)
'Fine, okay. Can't you think of something BIGGER?'
LOL! And of course five movies later in the Trek franchise they did come across the "Face of God" and Kirk asked this question - "If you're God, why do you need a starship?" Answers on a postcard please...... ;-)
