Laurie Metcalf has warned 'The Conners' won't be "completed" when it ends after seven seasons

She told People magazine: "There's a lot to wrap up and I think the writers are really working hard to get everybody's storylines sort of ... not completed.

"It's not going to have a big bow tied up with the Conners.

"And it will remain true to their storyline, what happens to them in the final episode. But, it's a very short amount of time to wrap up this many seasons of a family that's covered decades."

And Lecy Goranson, who plays Becky Conner, also noted there are no plans for the finale to involve "doing something wacky or kind of culminating."

She said: "It's just not really our style. Our show is about real people and real life situations, so I feel like we don't need to do that. It's enough just saying that the characters are moving on in the future together as family."

While the show is coming to an end, Lecy are Laurie are both hopeful it doesn't mean they won't work with their castmates or the crew again.

Lecy said: "I'm already thinking of the next thing for all of us, including the crew.

"I'm an optimist and I'm thinking, 'How do I keep us all together? I just refuse to believe that it's done."

Laurie added: "It would be interesting if we broke off in little groups and did other projects. And could see each other in different cameos on other things here and there. That'll be interesting."

Lecy believes 'The Conners' enduring popularity has been partly down to its "unique" tone.

She said: "I think we walk a line between drama and comedy that's very unique.

"And I think because of that, it's kind of surprising for the audience when things get more serious, more grounded.

"[We address issues] that are topical, that are hard to talk about sometimes, and we do it with comedy.

"I think the gravitas of it is unique to our sitcom, and it's what I hear ... I'll hear from friends and people on the street about jokes and what have you, but I'll hear a lot about scene work, situations that we're in, that it really gets to the core of people."
