The series also stars Rupert Grint, Nick Frost and Don Johnson. 
 
 Lindsay Lohan has joined Sky comedy Sick Note, starring Rupert Grint, Nick Frost and Don Johnson, for its newly announced second season. 
 
 Sick Note follows the story of Daniel Glass (Grint), a compulsive liar stuck in a failing relationship and dead-end insurance job, under the thumb of his boss (Johnson). Lohan will join the show, which airs on Sky 1 in the U.K., for season two as the daughter of Johnson's character. 
 
 The first season will air this fall, while the second season is currently shooting in the U.K. 
 
 In the first season, Grint's character is wrongly diagnosed with a terminal illness by his incompetent doctor (Frost) who convinces him to hide the truth of his misdiagnosis from colleagues, friends and family in a lie that spirals out of control. 
 
 The show is part of Sky 1's growing stable of edgier, grown-up comedies commissioned for the channel’s 10 p.m. slot. Other shows in the fall lineup for that slot include Bliss, from David Cross, starring Stephen Mangan and Heather Graham; and action comedy Bounty Hunters, from Jack Whitehall and Freddy Syborn. 
 
 Produced by British production firm King Bert, founded by producer Jo Sargent and writers and actors David Walliams and Miranda Hart, Sick Note is created and written by Nat Saunders and James Serafinowicz. Matt Lipsey (Little Britain) is directing. 
 
 Said executive producer Sargent: "We are thrilled to be making a second [season] of this nail-biting comedy and very excited to be welcoming the extraordinary talents of Lindsay Lohan to our all-star cast." ||||| Never a dull moment in the life of Lindsay Lohan and those she comes into contact with: Two Hollywood unions are investigating working conditions on the set of "Liz & Dick," the actress' Lifetime movie, after Lohan was found unresponsive and required medical attention and two crew members left the project. 
 
 "Liz & Dick" tells the story of Elizabeth Taylor and Richard Burton. Filming the project has proven somewhat difficult for Lohan, who was not only the subject of hospitalization rumors (Lohan was later said to be asleep -- not unconscious -- and never went to the hospital) but also crashed her car while driving in Los Angeles. 
 
 Two other crew members were actually sent to the hospital for exhaustion and dehydration. Lohan tweeted that she had been working 85 hours in four days. SAG-AFTRA confirmed to THR that they were looking into the matter and said they were not yet prepared to report their findings. Though IATSE declined comment to THR, sources said that union's agents were indeed looking into the matter. 
 
 As for Lohan, reports of concerned family members continue to surface. One industry source told The Huffington Post that Lohan was viewed as a "ticking time bomb," a macabre reference the source explained by adding, "If Lindsay hadn’t been making a movie, who would have called for help? As soon as filming wraps, she will be all alone again." 
 
 The 25-year-old actress is under a great deal of pressure to orchestrate a comeback before her star -- already tarnished by multiple run-ins with the legal system -- fades beyond repair.

– Lindsay Lohan is making a comeback on the small screen after a three-year hiatus from acting. The NY Daily News reports that the starlet posted a photo from the set of the British television comedy Sick Note announcing her new gig while posing in a blazer with a sleek bob haircut alongside costars Rupert Grint of Harry Potter fame and Nick Frost. Season one has yet to air (it's slated for this fall), but according to the Hollywood Reporter, the series follows Grint after he is misdiagnosed with a terminal illness; Lohan will come in during the second season. She is taking on the role of the daughter of Grint’s boss, who is played by actor Don Johnson. (Lohan made headlines last year while on a covert humanitarian trip.)
