The 1935–36Montreal Maroons season was the 12th season of the Maroons franchise in the National Hockey League (NHL). The Maroons finished 1st in the Canadian Division and lost in the Semi-finals to the Detroit Red Wings 3 games to 0. The first game of the series was the longest in NHL history, ending after 6 overtime periods.
On March 24, 1936, the first game of the Maroons-Red Wings series set a record for the longest game in Stanley Cup playoff history, as well as the longest ice hockey game ever played. The game began at 8:30 p.m. at the Forum in Montreal, and ended at 2:25 a.m.
After the 60 minutes in regulation, the Red Wings and the Maroons had both failed to score. With a completely blank scoreboard, the game went into overtime. It was not a spectacular game by any means. It was more a doggedly-fought defensive tussle, in which caution reigned supreme. Relentless back-checking prevailed throughout, stout work by the rival defencemen played a prominent part every step of the way, and backing it all up were the invincible displays of the goaltenders. The game had not even had that many penalties, with only eight in regulation and one to come in all of the overtime.
The overtime periods dragged on with the players becoming increasingly more exhausted. Despite the difficulties, one player managed to finally break the all-null tie. At 16:30 of the sixth overtime, Detroit rookie Modere Mud Bruneteau shot on the Maroons’ net, and the puck bobbled up over Lorne Chabot's foot to break the scoreless deadlock. The right winger had been called up from the Detroit Olympics for that season and then remained with the Red Wings until 1946. Detroit's goalie Normie Smith had been considered the team's weakest link, but he blocked 90 shots to earn the NHL's longest shutout. In total, the game lasted 176 minutes and 30 seconds.
