 "Q Who" went $ 50,000 over budget and at one point had an eighth day of shooting arranged, although this was subsequently cancelled. The overspending on this episode and "Elementary, Dear Data" resulted in the budget-saving production of the clip show "Shades of Gray". Director Rob Bowman was concerned with "Q Who" for a while, saying that "we didn 't know day to day if we were making a stinker or a winner".
