My fav. film drunk of all time, Richard E. Grant has made a film in Swaziland (the first ever?!) and has wrote a book about it:

The completion of a feature film is always something of a minor miracle. Turning the initial story idea into a workable screenplay is just one hurdle on a journey in which writers, producers, the director and his players must collaborate with hundreds of supporting film crew to create something that then has to fight for screen-time in the pitiless world of commercial theatrical distribution. The Wah-Wah Diaries tells the story of that creative journey in all its agonising detail, beginning with Richard E Grant's decision to write a script based on years of assembled notes "resembling a tax return in the middle of a nervous breakdown".

"What a piece of work is man indeed." Congrats Mr. Grant! (the Guardian)
