With the decision of making [Hex] in two parts in place, work increased a lot for the production team but as the budget was also increased, they were more than happy to do the extra work.
Actually, they were saying a lot by shooting the two parts at the same time.
It was more because of the fact that the decision had been taken in the middle of the shooting but it was still a great decision. If they had shot the two parts separately, the budget of 300 million dollars would have increased by another 100 million dollars.
Currently, as they were going for two parts, each part's production budget was around 150 million dollars which wasn't much.
Titan studios were keeping a close eye on the shooting and they were more than happy with the progress for now.
