It's difficult, while watching this Giovanni flick ,not to think of Jacques Becker's "le trou" (1959) ,the script of which he wrote.But whereas the heroes of Becker's masterpiece were digging a hole to escape from jail,the "heroes" of " les egouts" are digging a tunnel to rob a bank.The characters are not endearing ,former firebrands ,although the lead rather recalls some kind of "true life" Arsène Lupin ,but a humorless Lupin.One does not see why one should take an interest in those men (and woman).Robin Hoods ,they definitely are not.<br /><br />NB.Another version was made at about the same time "the great Riviera bank robbery" starring Ian McShane.The two versions were drastically different since that one showed the hero's paramilitary activities.
