All Creatures Great and Small first look teases day before the wedding

He tells her that the first time he ever saw her, he was so distracted he got off the bus at the wrong stop, to which she replies: "I remember wondering what you were up to!"

"I never imagined for a second this is where we'd end up," James adds as he turns to face Helen, who says simply: "Yes you did."

They then share a kiss before Helen gets on the bus and tells him she'll see him tomorrow.

As the bus drives off, Tristan (Callum Woodhouse) appears at James's side and jokes, "Still time to change your mind..."

James's response? "Not for anything in the world!"

The new season gets underway on Channel 5 on Thursday 15th September, and fans will no doubt be particularly looking forward to the wedding after the couple got engaged towards the end of season 2.

And star Nicholas Ralph has promised that it will be worth the wait, telling RadioTimes.com and other press that although he couldn't say too much, he "was smiling like a Cheshire cat from start to finish" when he read the script.

"Not only is it everything that you would hope it would be - romantic and touching in points as well - but it's also very funny," he said. "It's a really funny, funny script as well."

All Creatures Great and Small season 3 starts on Thursday 15th September at 9pm on Channel 5. Check out more of our Drama coverage or visit our TV Guide to see what's on tonight.
