Continuity Error

Whist editing today we discovered a continuity error in our first scene, in the shot walking towards our building, Josh isn't wearing glasses, however in the shot as he is walking up to the building door, he is. This is not too much of a problem as in the second shot he has his back to the camera and the glasses are barely visible. However the problem is still there and we are hoping to try and edit it so that if the glasses become too visible we can hide it. Unfortunately we would have liked to have re-filmed the shot all together, taking into account this error and aiming to fix it. However due to issues with timescale and actor availability, as well as possible threat further continuity mistakes we have taken the editorial decision to leave the shot in place. We hope that this issue will not be too much of a problem in the final cut of the film.
