Sneakers is a 1992 caper film directed by Phil Alden Robinson, written by Robinson, Walter F. Parkes, and Lawrence Lasker and starring Robert Redford, Dan Aykroyd, Ben Kingsley, Mary McDonnell, River Phoenix, Sidney Poitier and David Strathairn. It was filmed in late 1991 and released in 1992.

Lawrence Lasker and Walter F. Parkes first conceived the idea for Sneakers in 1981, while they were doing research for the script of WarGames.[1]

Once Robert Redford was attached to the picture, his name was used to recruit other members of the cast and crew, including the director Robinson, who had little initial interest in the project but had always wanted to work with Redford.[1]

At one point during the project, Robinson received a visit from men claiming to be representatives of the Office of Naval Intelligence, who indicated that for reasons of national security, the film could not include any references to “a hand-held device that can decode codes”.[1] Robinson was highly concerned, as such a device was a key to the film’s plot, but after consulting with a lawyer from the film studio he realized that the “visit” had been a prank instigated by a member of the cast, possibly Aykroyd or Redford.

The story of Sneakers, the movie and Len Adleman the mathematician is as follows:

Larry Lasker was one of the writers of the 1983 hit movie War Games. Based on that success, he started to produce his own movies. While looking for a new project, he called me at USC and we arranged to meet.

He was considering making a movie based on cryptography. While we spoke he mentioned that he was also considering a movie based on a new treatment for Parkinson’s disease. Patients who had been “frozen” for many years would wake-up under treatment – sort of a Rip Van Winkle thing. I said that that sure seemed a lot more interesting than crypto – and he disappeared. The next time I heard of him was in 1990 when his movie Awakenings, starring Robin Williams and Robert De Niro, appeared.

A short while later, Larry again made contact. This time he was well on his way to making Sneakers, starring Robert Redford, Sidney Poitier, Mary McDonnell, Dan Aykroyd and River Phoenix. He told me that there would be a scene wherein a researcher would lecture on his mathematical work regarding a breakthrough in factoring – and hence in cryptography. Larry asked if I would prepare the slides and words for that scene. I liked Larry and his desire for verisimilitude, so I agreed. Larry offered money, but I countered with Robert Redford – I would do the scene if my wife Lori could meet Redford.

I worked hard on the scene. The “number field sieve,” (the fastest factoring algorithm currently known) is mentioned along with a fantasy about towers of number fields and Artin maps. I was tempted to name the new breakthrough the “function field sieve” — since I was actually working on a paper at the time which would later appear with that title – but I decided against it, for reasons that escape me now.

I made beautiful slides on my Mac. This took a great deal of time (graphics programs were not as user friendly as they are now) but I wanted the stuff to look impressive. As it turns out, Larry had them redrawn by hand by some guy on his crew – he said that hand drawn slides looked more realistic. Of course he was right – but I could have saved a lot computer time had I known in the first place.

The lecture scene was actually shot at a small college in LA. Larry told me that some physics professor there saw the slides and said that they did not show math at all. He offered to redraw them for a small fee – Larry declined.

Lori and I were there when the scene was shot. I was most pleased with my phrase “a breakthrough of Gaussian proportions,” — the Prince of Mathematics could use a plug in a major motion picture. We were introduced to Redford and chatted with him for about five minutes – that is Bob and I chatted – Lori said hello and then apparently was too star struck to add more.

I was given credit at the end of the movie as (in my recollection) “mathematical consultant.” Anyway the Academy snubbed me – since apparently the mathematical consultant Oscar for that year went to someone else.
