do anybody fall for this in 1967. in that year i be eight year old and and i already hat this kind of crap . i would have be yell at the screen . i yell at the screen last night . perhaps this be the first heist film that use laser beam in a vault a an obstacle to thief and but why do they do it so badly . the laser beam and which criss cross the vault like a spider web and be do in an ostensibly clever way represent translucent tube fill with light . but when the thief climb over the beam with a fancy telescope ladder rig we can clearly see the laser beam sag . not just a little and either . bad and we can see a connection point where two piece of tube be join . it a friggin close up . this kind of sloppy craftsmanship really take you out of the film . it get bad . the safe be rig with a delicate noise detector . the sound of a cigarette lighter be enough to set it off . the solution . lift the entire safe with pneumatic lift and stick on little wheel and soundproof the wheel with shave cream ( i kid you not ) and and push the safe ten foot away from the sound detector . then start drill those titanium door . then blow it with nitro glycerin . then silently push the safe back up the ramp and into the vault ( more shaving cream ) and disconnect the pneumatic line and cart away your seventy five pound of equipment and and close the vault door . all without make as much sound a a zippo . this film be co produce by spanish and german and and italian film company . be it possible that in an audience of and say and 100 spaniard or german or italian and no one make a huge puk sshhh . sound when those air hose be disconnect . maybe not . maybe they be good at suspend disbelief than an eight year old american . compare this to the new gold standard for technical competence in that era of film making and 2001 represent a space odyssey . although history have unspooled very differently than as predict in 2001 ( no city on the moon and no manned exploration of other planet ) and those cinematic prediction be very carefully execute . the craftsmanship be exquisite . if the american and british who make 2001 have be as clumsy a the hack who make grand slam and there never would have be any discussion about the religious or spiritual meaning of that bizarre last act . those question be discuss very seriously in the late 60 ( and still be ) because 2001 be a believable world where our power of disbelief remain suspend for 2 half hour . now and of course grand slam be just a heist movie . it doesn not have any deep pretension . do that excuse it technical shoddiness . of course not . even a frothy story need to keep u within the wall of the story and so that we can be lie to convincingly . when fundamental fact be ignore and the movie be over . the confederate army can not wear blue . you can not drive to australia . and laser beam can not sag . maybe this be why the united state be the technological powerhouse of the world in the 1960 . we care about get it right . and we still do . even bad american movie be produce with a technical brilliance that outstrip the stupidity of the above the line talent . and web site like moviemistakes . com help keep our standard from flag . maybe grand slam deserve credit for inspire good film and such a the italian job two year later . perhaps you can insist that ocean twelve owe it dance laser beam to grand slam . but at least in the italian job when thing blow up they go boom . and and in ocean twelve the laser beam do not sag .
