It means that if they misunderstood Comfort and Joy, they misunderstood my other films.
I didn't think Comfort and Joy was going to be a box-office smash.
I think, unconsciously, I was addressing myself more with Comfort and Joy than with my other films to Scottish people.
So those who misunderstood Comfort and Joy the most were those who thought I was just trying to make a jolly farce.
