Producers searched for 6 months for a suitable bar until settling on 1806 wine and bar on Exhibition St in Melbourne, Australia.
The script went through 12 drafts, with the last 6 written in Cadiz, Spain. The first draft was about 25 pages and the last 7.
The original idea was to explore how different the male and female would think during a first date. The first half was going to be just the males inner monologue and then the second half, the females. It was decided to make the film a straight comedy and have the male as an awkward odd character who lives inside his head.
