Mushy romance crashes like the Titanic into the iceberg of sci-fi this Friday as The Time Traveller's Wife arrives on our screens.

It's loaded with Notebook-style yearning and troubled love, but we figured out what it's missing: Dr Emmett Brown.

Yes, Back To The Future's crazed scientist makes any time travel film seem more fun, so we thought we'd add him to the new arrival and some others from years gone by.

Or, if you have access to  time machine, years still to come. Or... Anyone got an Aspirin? We have a headache.

The Time Traveller's Wife (2009)

The Original: Winsome heroine Clare Abshire (Rachel McAdams) meets her perfect man in Eric Bana's librarian.

There's a hitch in their romantic plans, however  - due to a weird gene, he keeps vanishing to travel through time, which means she spends a lot of time alone.

But they keep the flame alive, even when their relationship is stretched to breaking point.

With Added Doc Brown: After his wife Clara is moved to tears by the couple's plight, Doc decides to intercede.

He creates a device that can lock someone in time and proceeds to grab Eric Bana.

Sadly, due to a minor miscalculation, he ends up transporting Bana's Star Trek villain Nero, complete with the Narada, back to modern-day Earth.

Risk To The Space/Time Continuum: The time stream is changed as Nero decides that our world is the perfect place to stop the birth of the Federation.

After a million hardcore Trekkers have fallen trying to fight him off (the gene pool remains singularly unchanged), King Nero The Pointy begins the new dark age as ruler of Earth.
