Underground (1970)

Accompanied by the tagline "Sabotage! Ambush! Kidnap! Into the Alleys! Into the Cellars! Into the..." Underground (1970) was a Bob Goulet action vehicle made during that very narrow window of time in which such things were possible. The only feature film ever directed by prolific 70s and 80s television director Arthur H. Nadel, the film follows Goulet's spy Dawson as he enters France late in 1944 and falls in with a team of French resistance fighters. Dawson's plan is to kidnap a high ranking German general, bring him to London and plant the narrative that this general is an informant working for the Allies. Accompanying Dawson on this mission and posing as his wife is Yvonne (Danièle Gaubert), who doesn't trust him one bit, particularly once she discovers that his last female partner was killed on a similar mission earlier in the war. Before the one hour mark, she comes around on him as that's where we get a relatively tame sex scene between Goulet and Danièle Gaubert! She is very clearly topless, we just aren't able to see her breasts as she mounts the bucking stallion that is Bob Goulet at the mustachioed height of his powers! Like most war pictures of the era—and this film most certainly belongs to the era that was coming to a close in 1970—there is a dearth of female speaking roles. Gaubert is actually the only female character with a name as the only two other women in the cast are Nicole Croisille, credited as "Bistro Singer," and Maura Keeley, credited as "Mother." Just stick with the good parts of this one here on Mr. Skin!
