he took the new episode on as a challenge, in the belief that the producers didn't think the episode would work well, which caused him to become determined to put out a good episode. he had numerous discussions with brent spiner, justman, and rick berman on aspects of the episode, and the technical requirements and effects required an additional day of filming. bowman credited spiner for making the episode work, giving one example, "he did the one scene in his own office with brent sitting down and lore discussing what it's like to be human. he did one side, we shot through a double, then turned around, read it the other way and shot the other half of it. those two characters in those scenes are different people... he really painted those characters differently." edits were still being made to the script during filming, as the writers wanted to introduce a new element to data, in order to further distinguish him from lore: an inability to use contractions. data had used contractions during earlier episodes, and spiner refused to shoot the scene until a final decision was reached; production stopped while there was a meeting on this subject between gene roddenberry, the producers, and the writers, in the middle of the bridge set.
