Question: Why couldn't the fuel cells be opened again once they were closed?
Answer:The reactant valves to the fuel cells could not be re-opened once they were closed (except by ground servicing) because they are very delicate and must be precisely calibrated. Although CAPCOM tells Lovell to manually close the valves for cells 1 and 3, they had already failed and closed so this had no effect.

Did they really try closing fuel cells 1 and 3 like in the movie?
