Neal Purvis and Robert Wade returned as screenwriters and completed a draft of the script by April 2007; Paul Haggis also worked on the script, completing it two hours before the 2007–2008 Writers Guild of America strike officially began. Further work on the script had to be undertaken by Forster and Daniel Craig, who said later, "We had the bare bones of a script and then there was a writers' strike and there was nothing we could do. We couldn't employ a writer to finish it. I say to myself, 'Never again', but who knows? There was me trying to rewrite scenes – and a writer I am not". Craig also admitted that the film was not initially meant to be a sequel, but it became one because of the re-writes undertaken by him and Forster. Haggis located his draft's climax in the Swiss Alps, but Forster wanted the action sequences to allude to the four classical elements of earth, water, air and fire. Michael G. Wilson decided on the film's title "Quantum of Solace" only "a few days" before its announcement on 24 January 2008. Forster hired Dennis Gassner as production designer, replacing Peter Lamont.
