Thanks for the feedback!
We were struggling to find good, reliable actors so we decided to act in it ourselves. This is partly why we chose the doc-style. All dialogue was improvised which is why (unfortunately) there is a lot of swearing, something we didn't pick up on while shooting.
We stupidly didn't keep proper accounts however I have found a doc stating we actually spent £1195 all together! The basement/office location cost either £200 or £400 for 2 weeks in there. We hired a van and crashed it which cost a fair bit
The gore cost around £200-£300. Lots of sandwiches bought. The booth cost around £100 to make. I already owned all the kit, the only equipment costs were some light gels.
The doc style meant we could make the film for basically nothing and spread it out over a year. We started by filming little bits every week before we went to the pub and it snowballed from there.
I've never heard of Dream Corp LLC. I'll have to check it out!
