On December 10, 2018, Clint Eastwood was photographed at the movie's Los Angeles premiere with his secret daughter Laurie. She identified herself to photographers as 'Laurie Eastwood'. The next day, Alison Eastwood confirmed on Instagram that Laurie is her half-sister. Laurie is believed to be the Washington-born Eastwood daughter who was given up for adoption in 1954, as alleged by biographer Patrick McGilligan in the heavily suppressed book "Clint: The Life and Legend" (1999) - an allegation no media outlet would repeat at the time. It has taken Clint 64 years to acknowledge Laurie.
It is based on The New York Times article "The Sinaloa Cartel's 90-Year-Old Drug Mule" by Sam Dolnick, which recounts the true story of Leo Sharp, a World War II veteran in his 80s who became a drug courier for the Sinaloa Cartel.
The release of The 15:17 to Paris (2018) and this movie mark the eighth time Clint Eastwood directed two features for release in a single year. The other years were 1973, 1982, 1990, 1997, 2006, 2008 and 2014.
Yves Bélanger's inclusion as cinematographer marked the first time Clint Eastwood did not work with Tom Stern as his cinematographer on a feature film in eighteen years. Stern worked as a gaffer on several of Eastwood's films from the 1980s into the early 2000s, before being promoted to director of photography on every scripted feature-length film by Eastwood, starting with Blood Work (2002) (Stern's first cinematography credit) to The 15:17 to Paris (2018) (Eastwood's earlier 2018 film).
Clint Eastwood's character Earl Stone drives thru a fast food restaurant named "Gunny's Burgers". Clint Eastwood played the role of Gunnery Sgt. Thomas Highway nicknamed "Gunny" in Heartbreak Ridge (1986), which Eastwood also directed.
In the history, the deliveries of Earl lead him in several States and the film follows it in these peregrinations at the wheel of his pick-up. To shoot the exterior shots, Clint Eastwood and a small team drove Earl's two pickups, the old and the new, during a three-day road trip toward the end of filming.
One of Earl's (Clint Eastwood's) handlers scolds him for speaking without being asked, by saying, "Mules don't talk!". Clint Eastwood's first credited movie role was that of "Jonesey", in Francis in the Navy (1955), which was part of the "Francis, The Talking Mule" series.
The Mule is not photographed by Clint Eastwood's favorite cinematographer, Tom Stern. This is a first since Blood Work (2002), the first collaboration between the two men. Canadian Yves Bélanger takes over instead.
Other footage has been shot elsewhere than in Atlanta, for example, in the Midwest cities' DEA offices, where Laurence Fishburne, Bradley Cooper, and Michael Peña's characters work, as well as the sites used for the home. Mary, the local veterans, the Ginny wedding reception room or a roadside motel. For the sequences in the tire shop that serves as a den of the cartel, the team traveled to New Mexico, and for the impressive property of Laton, a house was spotted in Las Cruces, and decorated to match the opulence and extravagance of the boss of the cartel.
Michael Pena, who plays Bradley Cooper's DEA agent partner, is in a very select group of actors who appeared in movies which were voted Best Picture Oscar winners. He was featured in Eastwood's 'Million Dollar Baby' and the following year's 'Crash.'
