Second Wind is a 1976 Canadian sport comedy film,[2] directed and edited by Don (Donald) Shebib, written by Hal Ackerman, and produced by James Margellos.

This was the first feature film starring role for actor James Naughton, who portrays a stock broker whose new jogging hobby turns into an obsession to excel at long distance running, straining his career and his relationship with his wife (Lindsay Wagner).

His new hobby also creates problems at work, distracted when he should be focused on a major deal, allowing an ambitious coworker to usurp his stature as the firm's golden boy.

As if that were not enough, an attractive woman named Paula (Tedde Moore) hits on him one day while he is out jogging, then tries to seduce him, testing his fidelity to his long-suffering wife.

"[3] In a 2013 interview with Sam Weisberg, director Don Shebib described the themes of the film: "I like what it says and what it's about, the guy chasing a dream, getting caught up in obsessions.

[7][8] Reginald H. Morris was pleased that there were no sets: "it was all shot in natural surroundings, in people's houses, in the stock exchange, in bars and so on",[7] in Toronto, Gravenhurst, and London, Ontario.

[7]Ordinarily, explained Morris, there is a certain difficulty with repeated takes under the shifting effects of the sun, the angles of sunlight and strength making match shots tricky.

[1] Its American premiere took place at the University of Iowa student-run Refocus film, video and photography festival on 17 April 1976, with Shebib in attendance.

[14] Michael Walsh gave Second Wind an overwhelmingly positive review, calling it a "wonder", "an exciting, stylish picture that can be enjoyed by the whole family" and a "first-class film".

Walsh hails the direction, the script, the cinematography and especially the cast, who are "little-known but solidly professional performers who put it across to near perfection", reserving particular praise for Naughton.

"[3] Maurice Élia echoed many of Jackson's impressions: the story itself is quite original and a source of inspiration in some sense, and, for the first time (on the screen or off), Toronto actually looks good (perhaps to the point of exaggeration).

[19] The characters are "drawn fairly well" (Hanson notes that Hal Ackerman went on to become a popular screenwriting teacher at UCLA's film school), "and some of the dialogue clicks, especially passages of sarcastic banter.
