Hellfighters (1968)

The head (John Wayne) of an oil well fire fighting company is reunited with his estranged daughter (Katharine Ross) after being seriously injured in an accident. But when his daughter marries one of his employees (Jim Hutton), it causes complications not only with him but with his estranged wife (Vera Miles). Despite being a John Wayne film, this isn't really an action film but mostly a domestic drama interspersed with some well made action sequences. The fire sequences are really impressive and more than make up for the tedious arguments of whether wives should or shouldn't accompany their husbands on their dangerous missions. The excellent special effects work and exterior locations (Wyoming standing in for South America) give it a more polished look than the usual Universal TV backlot look most of Universal's 60s films of the era had. Directed by Andrew V. McLaglen. With Bruce Cabot, Jay C. Flippen, Barbara Stuart, Valentin De Vargas and Laraine Stephens.
