Sure! Here’s the task completed with the verbs in the correct forms:
We (1) were shooting the film for two hours. It was a cold grey winter morning and the things (2) were not going smoothly. I (3) heard that the cameraman (4) was cursing under his breath - his camera (5) had refused to work all the vital spare parts he (6) had found. If he (7) had looked for so long, his camera (8) would have worked much better, but now since the cold (9) was affecting the camera, he (10) found it hard to operate it. By that time the director (11) had already given up any hope of finishing the shooting by lunchtime as it (12) was not expected. Only when it (13) got warmer did the filming resume and the things (14) went faster. All the work (15) was done by three that afternoon which, I think, is not bad considering that we hadn't started until nine.
Feel free to ask if you need further assistance!
