Stiles and Lydia
Towards the beginning of the series, Stiles innocently kisses Martin on the cheek in a rather intuitive manner. Lucky for him, it made it into the episode.

The decision put Stile’s character in a new light. Given the response from fans, the showrunners then decided to work in a full-blown love story for the two characters in the series.
Owen and Claire
On the last day of filming, the director pulled Pratt aside and suggested that he kiss Howard in the final take of that scene. In order to get the best reaction, the director didn’t warn Howard about the kiss.

The surprise kiss (which happened to be in front of 200 people on set) was a smart move by the director as it landed in the final cut and was a great moment for the audience.
Teen Wolf
MTV series Teen Wolf focuses on a small town where high schoolers encounter supernatural events. The nerdy and socially awkward character of the show, Stiles Stilinski (Dylan O’Brien) is smitten with one of his peers, the beautiful Lydia Martin (Holland Roden).

However, Stiles would have almost missed his chance at romance if he hadn’t gotten over his shyness.
The Hunger Games: Mockingjay – Part 2
At the end of the Mockingjay Part Two (the final film in The Hunger Games series), Effie Trinket (Elizabeth Banks) and Haymitch Abernathy (Woody Harrelson) share a sweet kiss on the cheek and then on the lips!

Later it was revealed that a kiss was never a part of the scene but was, rather genuine gesture on Harrelson’s part.
Effie and Haymitch
Harrelson confessed that he had a crush on Elizabeth Banks and may have used this scene as an opportunity to make his personal dreams come true.

While one actor may have been a little more invested in the romantic moment than the other, both made it work for the sake of the scene.
