There were times when filming corporate interviews in front of green screen was the order of the day. It was mainly driven by the fact that we would often have to film interviews in horribly empty, soulless offices or board rooms.
It was always visually challenging to make the background look appealing, when all you had was a white wall and dodgy pot plant. Many directors preferred green screen so they could add decent, more appealing backgrounds in the post. Then along came large format cameras with shallow depth of field and the problem of boring backgrounds became less important. You can now create nice effects with less lighting and hassle by making the background drop off into shallow focus.
