Sellers died in late July 1980, a year and a half before production began. After Sellers died, UA tried to get
Dudley Moore to take on Clouseau in the Sellers-penned
Romance of the Pink Panther. Moore refused to do it without Edwards directing and was willing to play Clouseau only one time as a tribute to Sellers (knowing
Romance was to have ended the series, according to a
Los Angeles Times interview with Moore in 1980). UA wanted the series to continue, but Edwards refused to cast another actor as Clouseau, recalling the negative reception that
Inspector Clouseau (1968) suffered upon release (The production featured
Alan Arkin in the title role and was made without the involvement of Edwards and Sellers), and also believing that no one could actually, realistically and believably replace him in that role. Edwards instead opted to reconstruct Sellers's performance from deleted scenes from
The Pink Panther Strikes Again.
Frank and
Tom Waldman wrote the screenplays for both
The Trail of the Pink Panther and its sequel
Curse of the Pink Panther together, and they were
produced back-to-back on a $17 million budget. Principal photography began on February 15, 1982, at
Pinewood Studios and concluded on June 15, 1982, in
Paris. Additional filming took place in
Nice,
Valencia,
Ibiza,
Cortina d'Ampezzo, and
Casablanca. The shooting in Valencia was guarded by the Spanish
National Police Corps and the
United States Secret Service due to the involvement of President
Ronald Reagan's daughter
Patti Davis. Footage of the fictional country of Lugash was filmed in Paris, including the
Basilica of Sacré-Cœur in
Montmartre. Despite this, however, there was a practical reason behind Frederick's suing of Edwards. Her primary objection was that Sellers had actually vetoed the use of outtakes from earlier
Panthers in his lifetime and that his estate should have had the right to control the use of outtakes after his death. The reason the question of outtakes being used had come up in Sellers's lifetime was that Edwards had shot and edited a two-hour and six-minute version of
Strikes Again, hoping to recapture the zany spectacle of
The Great Race, with Dreyfus as the melodramatic villain in the fashion of Jack Lemmon's Professor Fate.
United Artists vetoed this long version and the film was drastically cut from two hours to just over an hour and a half. There were rumors for a time that a three hour cut existed as well, but
Strikes Again's novelization clears this all up as, apart from some minor deviations, it contains all of the deleted scenes that were ultimately used in
Trail, which only total to about 23 minutes and no other additions that would total to an extra hour's worth of footage are present in the novel. A London court subsequently ruled that the use of footage was illegal and awarded Frederick $1.475 million in damages but declined to bar the release of the film. ==Original plans==
