Peter Falk in his 2006 auto-biography 'Just One Thing: Stories of My Life' states that he didn't like the script for this movie which he thought was hackneyed and full of cliché. Falk wanted to leave the film for these reasons. However, producer Dino De Laurentiis encouraged Falk to stay by giving him film poster name-above-the-title credit as well as choice of writer for his dialogue. Falk stayed on the picture and apparently actually wrote his own dialogue.

The meaning and relevance of this movie's title "Anzio" refers to the Battle of Anzio on 22 January 22 1944 during the Italian Campaign of the Second World War. The Battle of Anzio was an amphibious assault against the Axis allies of Germany and Italy in the Italian regions of Nettuno and Anzio. The name of the World War II military mission that resulted in this combat was Operation Shingle. This operation was aimed at outflanking the German army on the Winter Line and as such allow for an assault on the capital city of Rome, Italy. Operation Shingle was lead by Major General John P. Lucas

Location filming for this movie was conducted in and around the environs of Rome, Italy.

Toward the beginning of the film, Cpl. Jack Rabinoff (Peter Falk) is in the back of a Red Cross ambulance with three prostitutes. Rabinoff grabs a shoebox-sized box labeled "Hershey's Milk Chocolate Multi Pack" with a "1968 design" of the Hershey logo. One of the prostitutes reaches into the box and pulls out a "1968 design" box of Brach's Milk Chocolate Stars. In addition to the two anachronisms, Hershey's and Brach's are two separate companies.

When Ennis's jeep first drives into Rome it drives down an alleyway passing buildings with roller doors on them. Roller doors where not invented until some time in the mid-'50s.

Two different figures are given for the casualties suffered by the Rangers during the ambush - 776 and 767 (+ 7 survivors).

Dick Ennis: [attending to Rabinoff who went into sudden convulsions] Look, fellows, I think he can use the air more then the company, okay? Anything anybody can do?

Dick Ennis: [talking on the radio intercom] Hello beachhead. this is Dick Ennis.I'm somewhere in the Alban Hills with the survivors. Sorry to take you away from the gaming table general, but I thought you should know you lost a couple pins off your chart. 1st and 2nd Rangers battalions have been wiped out. Did you read that? Of 767 men, there are 7 survivors left to see the result of one more royal foul-up. but this one's unique. This didn't happen because a general was too reckless. But because a general was too cautious! How about that? An entire outfit wiped out because the general was timid. I know it rarely happens that way general, but it sure as hell happened here. A timid general. He walked them into a park and left them in a graveyard.

Dick Ennis: [referring to a radio that went dead] Ain't that a bitch? A dumb, dirty stupid useless bitch!
