I woke up early yesterday morning with a sudden thought that I couldn’t figure out the answer to. You know Coronation Street? (If you don’t watch it, stick with me, because it’s a universal soap question really). The character of Bethany (a little girl of about three) is played by twins, so that it’s not too stressful for them, all the long hours and such. But what happens if the same actors want to continue the part as she grows up… when she’s old enough they’ll only need one person to play Bethany.
