From cast shakeups and historic milestones to a whole new start for Claire Underwood, we round up what to watch this fall

The 2018/2019 television season has launched, and with it comes a flood of returning favourites as well as new programming on streaming services that you'll want to add to your must-watch list. Dates, times and shows subject to change. Check your weekly listings.

Here are 10 newsworthy shows to note...

1. Forever – Amazon Prime Video

ForeverAmazon StudiosSNL alums Fred Armisen and Maya Rudolph play a couple whose suburban life finds them in a rut after 12 years of marriage—until the decision to shake things up by taking 
a ski vacation places them in thoroughly unfamiliar territory.

Premieres: Friday, September 14th

2. The Big Bang Theory – CTV & CBS

Big BangCTVYou say Bazinga, we say goodbye! CBS has confirmed season 12 will be this geeky sitcom’s swan song. While several cast members had been hinting at this possibility of late, per a report from Entertainment Weekly, it was four-time Emmy winner Jim Parsons who put the final nail in the coffin
 after he made it known he wasn’t interested in continuing. The show will end its run with 279 episodes, the largest total for a multi-camera comedy in TV history. This season picks up with Sheldon and Amy honeymooning in New York. Meanwhile, Penny and Leonard find they’re disturbingly similar to Amy’s parents (guest stars Kathy Bates and Teller) and Raj gets into a Twitter war with Neil deGrasse Tyson—the first of what will no doubt be a cavalcade of geek icons stopping by to bid Big Bang adieu.

PREMIERE: Monday, September 24th

3. Lethal Weapon – City & Fox

Lethal WeaponCityThe second season was thrown into turmoil with reports of star Clayne Crawford’s out-of-control behaviour on-set and conflicts with co-star Damon Wayans. The result: Crawford was axed and American Pie alum Seann William Scott brought in to replace him for season three. With the exit of Crawford’s character presumably addressed in the season premiere (he was shot in the season-two finale), Scott will play Det. Wesley Cole, “a former international CIA operative who has been everywhere and seen everything.”

PREMIERE: Tuesday, September 25th

4. This Is Us – CTV & NBC

This is UsCTVArguably still the most-buzzed show on network TV, This Is Us returns for season three, and the writers are ready to start pushing narrative boundaries. Said co-showrunner Isaac Aptaker at the TCA this year: “A typical episode of This Is Us has three sibling storylines and then a past episode, and every now and then we’ll devote one solely to one character, but this season we’re really throwing everything out the window and saying all bets are off. So maybe we’ll do an episode where every act is a different time. Maybe we’ll have something that jumps five timelines in an episode. We’re really pushing the limits of what people will comprehend.” As for specifics, we know that we’ll get to see a lot more of Jack’s backstory (“In many ways, Jack may be the character we still have the most to learn about,” said creator Dan Fogelman in a previous interview), including his time in Vietnam with his brother (guest star Michael Angarano). We’ll also see Jack and Rebecca’s pre-marriage courtship, and learn how Rebecca found love again with Miguel decades after Jack’s death.

PREMIERE: Tuesday, September 25th

5. Modern Family – City & ABC

Modern FamilyABCWhile Modern Family exec producer Steve Levitan had previously declared that this season—the 10th—would “probably” be the last, ABC has yet to make a definitive decision. However, fellow ep Christopher Lloyd says cast and producers “are open” to further seasons, admitting “it’s a complicated discussion, and that discussion is taking place.”

Meanwhile, Lloyd teased some storylines for the upcoming season. “Big relationship changes, some life and death, one family faces death 
for the first time, which is a big point for us,” he told Deadline. “Pretty significant changes in the lives of a couple of the Dunphys. One big 
farce we will be doing which will be our Christmas show, and then some ridiculous things like Phil Dunphy struggling with a pretty good certainty that he was an unwilling spy for the Russians when he was in high school.”

PREMIERE: Wednesday, September 26th

6. Law & Order: SVU – CTV & NBC

LOSVUNBCLook for an appearance by Carl Weathers, reprising his Chicago Justice role of State’s Attorney Mark Jefferies, in addition to recurring turns from Nip/Tuck alum Dylan Walsh, Scandal’s George Newbern (as a new love interest for Rollins!) and Rise’s Mark Tallman as the fiercely ambitious new chief of detectives.

Other guest stars will include Alec Baldwin—returning as Karen’s (Megan Mullally) adulterous love, Speechless star Minnie Driver (reprising the role of Karen’s stepdaughter/nemesis Lorraine Finster), Olympic figure skater Adam Rippon, Jon Cryer and former Friends star David Schwimmer, who’ll recur as Grace’s new love interest.
