The scenes of Harry Lime in the sewer were shot on location or on sets built at Shepperton; most of the location shots used doubles for Welles.<ref name="Documentary">{{cite web|url=https://www.bbc.co.uk/bbcfour/documentaries/features/shadowing-third-man.shtml|title=Shadowing the Third Man|publisher=[[BBC Four]]|work=documentary|date=December 2007|url-status=dead|archive-url=https://web.archive.org/web/20080420120218/http://www.bbc.co.uk/bbcfour/documentaries/features/shadowing-third-man.shtml|archive-date=20 April 2008}}</ref> However, Reed claimed that, despite initial reluctance, Welles quickly became enthusiastic and stayed in Vienna to finish the film.<ref>Noble, Peter.

According to the 2015 recollection of assistant director [[Guy Hamilton]], Greene and Reed worked very well together but Welles "generally annoyed everyone on the set". His temporary absence forced Hamilton to step in as a body double, and the filming of the sewer scenes was moved to studios in the UK as a result of Welles' complaints about shooting in the actual sewers.<ref name=FT>{{cite news | last = Aspden| first = Peter| title = Sewers, zithers and cuckoo clocks| newspaper = Financial Times| pages = Arts 16 | date = 13<!--/14--> June 2015| url = https://www.ft.com/content/e1adc13c-0e8c-11e5-9ae0-00144feabdc0 }}</ref>

Reed had four different camera units shooting around Vienna for the duration of the production. He worked around the clock, using [[Amphetamine|Benzedrine]] to stay awake.<ref>{{cite web |last=Feehan |first=Deirdre |url=http://sensesofcinema.com/2003/great-directors/reed/ |title=Senses of Cinema – Carol Reed |publisher=Sensesofcinema.com |access-date=2 September 2013 |archive-url=https://web.archive.org/web/20130604003559/http://sensesofcinema.com/2003/great-directors/reed/ |archive-date=4 June 2013 |url-status=dead }}</ref>
