"Monday Night Mayhem" is extremely entertaining, even for viewers who don't have much interest in football. My wife falls into that category, and she really enjoyed it.
This was originally a made-for-TV movie (TNT network) depicting the formation and early years of ABC's Monday Night Football. It's fast-paced, funny, occasionally moving, and always interesting. The script is heavily based on the book of the same name, which I would also recommend (authors are Bill Carter and Marc Gunther).
The movie's focus is on Howard Cosell. John Turturro is absolutely terrific as Humble Howard, America's most beloved and most hated sportscaster. John Heard as Roone Arledge turns in an excellent job, too. The rest of the cast is nicely filled out as well. Having several old MNF games from the 1970s on videotape, I can attest that the makers of the movie put a lot of effort into getting the look of the times just right. The soundtrack also does a nice job of bringing those years to life.
I'm fortunate to have grown up watching MNF in the '70s and remember fondly the magic of the early years when MNF was so cutting edge. In those days before cable, there was nothing else like it on TV. As an earlier reviewer put it, it would be nice if another Howard Cosell came along to liven up Monday Night Football again, but it's safe to say there will never be another Howard Cosell.
I highly recommend this movie, both for older folks like me who will enjoy the nostalgia, and for the younger generations who can get a taste of what they missed.
