Trainspotting

Trainspotting was released in 1996, and it is based on a Scottish Novel. Their budget was £3.5 million for the whole production of the movie.
They had a good set of crew:

Director: Danny Boyle
Writer: Andrew MaDonald
Producer: John Hodge

Pre-production

Rights to screenplay:
To be able to use the Scottish novel for their film, they had to gain access to the script and be able to use it themselves. This involves negotiation with the original author of the book. As John Hodge was coming up with his version of the script for the movie, the others were struggling to gain rights for the screenplay, which was a huge problem. This was because it has already been sold to other people, meaning they all had to agree on being allowed to use it for a movie. They were eventually able to use it in exchange for 2% of budget (£30,000).

Finance:
The film makers got offered £250,000 from a Hollywood mogul Scott Rudin. Channel 4 also helped to finance the film, covering the whole thing.

Casting:
Firstly they got onboard was Ewan McGregor. Next, they knew they wants Ewan Bremner and Bobby Carlyle. For particular scenes they need more people, for example the dight at the bar they needed 90 extras, including 10 in the fight.

Rehearsals:
They spend most their time rehearsing at the top of a Glasgow Tower Block, as it was filmed mostly in Glasgow anyway, however set in Edinburgh. Most the actors didn't do this because they were only doing 1 or 2 days filming anyway.

Location:
After the crew was assembled, they had to go out scouting locations for exterior scenes. Firstly they find a bar with a balcony area which is perfect for many scenes for them. They had problems with lighting and scenery, so they had to cover some lightbulbs to block some light out, or else it would make the quality of filming decrease. 1 day there would cost 500-1000 pounds. In various scenes they had to switch up the colouring and the lighting. Next they went to the Volcano Nightclub, where they painted in purple for a neon effect.Other places are used such as factories and toilets.

Props + costumes:
Over 98% of props they bought was cheap junk. This makes sure that they are not spending too much money on the less important things, and have more to spend on actually filming the movie. In fact, most of the stuff is there own clothes from the 80's that they had away somewhere.
