The Big Circus

The Big Circus is a 1959 film starring Victor Mature as a circus owner struggling with financial trouble and a murderous unknown saboteur. It was produced and co-written by Irwin Allen, later known for a series of big-budget disaster films.
Plot.
After splitting from his partnership with the Borman Brothers, Hank Whirling (Mature) needs a bank loan to keep his Whirling Circus going, now in competition with the Bormans. He gets it from a stuffy New York City bank, but only on the condition he take along accountant Randy Sherman (Red Buttons) and publicist Helen Harrison (Rhonda Fleming) to help the circus turn a profit.
Hank's top act is the Colino trapeze troupe, featuring family patriarch Zach Colino (Gilbert Roland), his wife Maria (Adele Mara) — affectionately called “Mama” by Zach — and newcomer Tommy Gordon (David Nelson). The circus also features ringmaster Hans (Vincent Price) and clown Skeeter (Peter Lorre). Unknown to Hank, his little sister Jeannie (Kathryn Grant) has nurtured a lifelong ambition to be a trapeze artist and has been secretly training with the Colino act for the past year.
At a press party thrown to celebrate the start of the circus season, a lion is let loose, terrifying the VIPs in attendance until Hank manages to capture it with the help of Colino. Helen accuses him of staging the incident for publicity. Subsequently, they discover the lion's cage had been deliberately opened by an animal trainer named Slade who used to work for the Bormans and whom Hank had recently turned down for a job. Slade is found, captured and eventually jailed.
Harrison and Sherman are infuriated by Whirling's refusal to accept their help. Hank and Helen clash over the best way to publicize the show; he feels she is intruding on his turf because he actually IS a very good publicist. Hank and Randy clash over Randy's firing of 40 roustabouts and replacing them with a stake-driving machine that expedites raising the Big Top. The machine is sabotaged and sets a pile of hay on fire; only swift action by Hank keeps the main top from burning. Hank, Helen and Randy begin to wonder if a saboteur, perhaps hired by the Bormans, is riding with the show.
Tragedy strikes when the first section of the circus train derails en route to a new stand. Mama Colino, the show's "den mother," is killed, leaving Zach Colino heartbroken. He loses his nerve and is unable to go on. As he is the star of the show and the show's publicity is built around him, this is a major disaster. Coupled with the foul weather they have been enduring for weeks that keeps the circus goers at home, the books are looking grim. Only glib talk by Sherman keeps the bank at bay and the show on the road.
Hank conceives a bold scheme. He will scrap the route he had laid out, do one show in Buffalo, New York, and then slip into New York City three weeks before the Borman Brothers Circus, stealing the audience from his rival. But to make his plan work, Whirling needs a major publicity splash. Helen proposes a stunt last performed in the 19th century: a walk across the gorge at Niagara Falls on a tightrope. Since Zach has lost his confidence in the wake of Mama’s death, Hank goads Zach into making the wire-walk by calling him a coward. Colino swears that first he will walk the Falls, and then he will kill Hank. But after completing one of the most dangerous wire walks in history, Zach realizes Hank said what he said only to help him, and they reconcile.
With the bank about to foreclose, Hank goes to television star Steve Allen to seek needed publicity for the circus. Allen buys the rights to broadcast the opening night performance in New York City for enough money to pay off the show's line of credit and enable it to go on. When detectives from the New York Police Department arrive on the lot looking for Tommy, the Colino Troupe's catcher, they inform the show's management that Tommy is an escaped lunatic. Hank realizes that Tommy is the saboteur who has been traveling with the circus and who is behind Mama Colino's death.
Meanwhile, Jeannie Whirling's debut with the Colino Troupe almost becomes her final performance when Tommy deliberately misses a catch, but she manages to grab onto one of the climbing ropes. While fleeing from Zach Colino, Tommy falls to his death. Down below, with the circus in the black and the saboteur dead, Hank and Helen realize what has been obvious to everyone else in the circus: they are in love with each other.
Production.
Allen announced the film in 1957. He was going to produce and direct for Columbia and intended to have parts for 40 stars, similar to how he made "The Story of Mankind". He wound up making the film for Allied Artists.
Filming started in January 1959 at the MGM studios. Allen was interested in making "an exciting colourful show - something the public can't see on television." Filming took place in early 1959.
Famed circus performer Barbette served on the film as a consultant.
Comic book adaption.
A comic adaption, Dell Four Color #1036, was released in August 1959.
