The relationship between Hayden Christensen and Natalie Portman in Star Wars has been voted the "most unconvincing" by film fans in a new survey.

The two played Senator Padme Amidala and Anakin Skywalker in Attack of the Clones. Audiences were not convinced that there was enough electricity between the pair to tempt Skywalker from his Jedi vows.

But the soggy couple were in esteemed company, according to the poll, which surveyed 3000 movie-goers for film advertising company Pearl and Dean to find the movie couple with the most unconvincing on-screen chemistry.

Some (once) real-life couples fared barely any better.

Ben Affleck and Jennifer Lopez, then the duo dubbed Bennifer, came in second for their uncomfortable performances in Gigli, while Tom Cruise and Nicole Kidman earned a mention for Eyes Wide Shut.

Affleck landed a second top-10 mention for his outing with Kate Beckinsdale in Pearl Harbour.

Hugh Grant and Andi McDowell took sixth place with Four Weddings and a Funeral.

Orlando Blom and Keira Knightly didn't steal audience's hearts in Pirates of the Caribbean, with their performance described as "too stiff upper lip".

The 39-year age difference between Sean Connery and Catherine Zeta Jones wasn't lost on the survey's respondents, who failed to respond to their pairing in Entrapment.

Unsurprisingly, Madonna was on the list - her relationship with Adriano Giannini in Swept Away didn't exactly sweep viewers off their feet.

But the passion between Heath Ledger and Jake Gyllenhaal in Brokeback Mountain was keenly felt, with 95 per cent of viewers convinced by their characters' gay romance.

The movie couples with the most unconvincing on-screen chemistry:

1. Natalie Portman & Hayden Christensen - Stars Wars: Episode II
2. Jennifer Lopez & Ben Affleck - Gigli
3. Keira Knightley & Orlando Bloom - Pirates of the Caribbean
4. Madonna & Adriano Giannini - Swept Away
5. Catherine Zeta-Jones & Sean Connery - Entrapment
6. Andie MacDowell & Hugh Grant - Four Weddings and a Funeral
7. Kate Bekinsale & Ben Affleck - Pearl Harbor
8. Nicole Kidman & Tom Cruise - Eyes Wide Shut
9. Jake Gyllenhaal & Heath Ledger - Brokeback Mountain
10. Kate Winslet & Leonardo DiCaprio - Titanic
