Ah, the seventies. Bad hairdos, ridiculous clothes, danceable but quickly forgettable music ... and lots of attitude, greed and drugs.
This is the era captured pretty well in the 2011 Canadian film "Funkytown," which follows the disco scene in Montreal during the period 1972-1980, based loosely on actual events. The story is told through the stories of various deeply-flawed characters, including the city's #1 popular disco DJ and TV host (who has a serious cocaine problem), a young man thrilled to be dancing on TV with his girlfriend (but secretly harbors a secret: he's gay and deeply in denial about it), a record producer desperately searching for one last star to promote, and a son who is deeply afraid of his father who controls his livelihood. The story is realistic for the period, though quite dark overall. It even briefly covers the growing discontent with disco, and popularity of punk rock as its replacement trend.
US television audiences may recognize Justin Chatwin ("Shameless" who played a gay kid on "Weeds" in the first and final seasons), who is believable as the confused young man. The rest of the cast seems equally capable. The direction seems a bit off, and it is sometimes confusing to follow, since the dialogue is a mix of French and English (often from the same actor in the same scene, which I am told actually happens in bilingual Montreal), with English subtitles. The soundtrack of dozens of classic disco tunes will touch a nostalgic vein among those who are old enough to remember this era. Unrated, would be an "R" due to sexual content and violence. I'm a bit generous with a four star rating (out of five), but I applaud the effort and largely-capable results.
