One of the several adventure films Roger Moore appeared in during his James Bond tenure and indeed there's a bit of a Bond family thing going on here as the director Peter Hunt had directed On Her Majesty's Secret Service (1969) and the titles are by Maurice Binder who is famous for his 007 opening title sequences. That aside this is an adventure film with doses of comedy in a Fordian style intermixed with some quite brutal violence the contrast making for a confused film that never really decides what it's trying to be. Set in 1913 in East Africa and alcoholic ivory poacher Flynn (Lee Marvin) teams up with handsome aristocratic Englishman Sebastian (Moore) and harasses the stereotyped German commissioner across the river. When war breaks out a year later the two sides go all out to kill the other and it all comes to a climax when the two heroes decide to blow up a German battleship. There's a love interest for Moore with Barbara Parkins as Flynn's daughter and plenty of nasty violence that at times is a bit unnecessary and Marvin gets a Wild Bunch moment, ironically considering he was Sam Peckinpah's first choice to star in that classic.. It's an overlong film and very of its time making it one for those nostalgic for 70s cinema and/or fans of Roiger Moore but otherwise it's mediocre when viewed today.
