Even if he ultimately proves to be the second coming of Jesus Christ, the eternally youthful Michael J. Fox will forever be Back to the Future 's Marty McFly in my eyes. Since being diagnosed with Parkinson's disease in 1991, the Canadian-American actor has heroically battled the illness and, after quitting popular sitcom Spin City in 2000 as his symptoms worsened, Fox's subsequent television cameos - most notably in Boston Legal and The Good Wife - have neither begged for sympathy nor whiffed of self pity. Finally, he is making a full-time return to the small screen, and his new traditional family sitcom, The Michael J. Fox Show (TVB Pearl, tonight, 8pm), seems to hold a giant mirror up to the life of the fantastic Mr Fox. Having being diagnosed with Parkinson's, America's favourite news anchorman, Mike Henry (Fox), has been retired from the spotlight for five years and spending quality time with his family. But his micro-management of the clan, however well-intentioned, has driven them all a little crazy, and Henry's wife, Annie (Betsy Brandt, Breaking Bad ), has conspired with his former boss, Harris Green (the criminally underused Wendell Pierce; The Wire ), to give him a subtle push back to work. As he has done throughout his career, Fox delivers his sarcastic retorts with perfect comic timing but, unfortunately, they are few and far between and the show gets its few laughs from making light of his disease. It is certainly admirable that Fox can laugh at himself and his illness but The Michael J. Fox Show - a Modern Family wannabe - is a one-trick pony that is ridden too hard into a saccharine swamp of smug family preachiness. Of course, I would instantly forgive Fox any number of crappy sitcoms for just one ride on Marty's hoverboard. From a movie star of the 80s to a pair of present-day Hollywood A-listers. Woody Harrelson and the reinvented Matthew "serious actors don't take their shirts off" McConaughey star in HBO's brand new eight-episode cops-and-killers drama True Detective (above; HBO, tonight, 9pm). Directed by Cary Joji Fukunaga ( Sin Nombre ), the series was shot on 35mm film, which gives it a hauntingly bleak feel. It is 2012 and in the dark, swampy spookiness of deep south Louisiana, two former detectives - gregarious family man Martin Hart (Harrelson) and the deeply troubled yet stoic Rust Cohle (McConaughey), who share an obsession for justice - are interviewed about the ritual murder of a prostitute in 1995. This is more of a twisted manhunt thriller than a regular whodunnit, the action switching between the original investigation and their current-day questioning as the disparate ex partners' volatile relationship and personal lives begin to unravel. Don't let the slow pace and awful moniker deter you. The show's brooding melodrama comes less from the crime and violence and more from the darkness within the two men as they face up to who they truly are. Good friends in real life, McConaughey underplays his role to sombre perfection and Harrelson is equally compelling, as are the rest of the talented cast. You don't need a time-travelling Delorean to tell you True Detective will be taking home some awards later this year.
