I say this because I have a much closer connection with the series than any project I
have worked on before.

It was an idea that came from a conversation with Ricky Gervais and Stephen Merchant whom I'd first worked with on Extras.

We talked about approaches I was getting from documentary producers wanting to follow me and my family.

This type of thing was not for me, but maybe it would be fun to manipulate my world as an actor and person, presenting a very different version of myself and my life.

And so, Life's Too Short was conceived - a faux documentary following a man obsessed with fame, a man whose career is on the slide, a man whose wife is divorcing him, a man who just happens to be short.

Filming the series was one of the hardest things I've ever done, but it was also the most fun.

For me, it was a chance to pay tribute to my comedy heroes and influences: Laurel and Hardy, Frank Spencer and Captain Mainwaring, who had all been childhood favourites.

Alan Partridge and David Brent set the standard in comedy characters.

Life's Too Short was my opportunity to enter their arena, to see if I had what it takes to stand shoulder to shoulder (in reality, shoulder to knee) with these legends of laughter.

But did I have what it takes? Ricky and Stephen seemed to think so, trusting me
with their seven brilliantly written scripts.

However, I knew that a bad performance could not be disguised by great dialogue or well realised comic situations.

I had to pull this off, there was too much at stake - Ricky and Stephen's reputation, the BBC's money and I knew expectations were very high.

As the start of shooting approached, I buried myself in the scripts. Every waking moment was spent learning.

I downloaded them all so wherever I was, I'd be able to study. In the car (not driving), walking, on the train, on the toilet - I was a man obsessed.

The first day of shooting was amazing. I was starring in my own sitcom for the
BBC, written by, directed by and co-starring Ricky Gervais and Stephen Merchant. Wow! This really is as good as it gets.

To shoot the seven half-hour episodes took eight weeks, and there was not a scene that I didn't appear in.

Each day presented new challenges, wonderful cameos from A-list stars and some lesser known, but equally talented performers. They were all a joy.

Johnny Depp came in on the last day of filming.

There was an air of anticipation before his arrival. Even Ricky and Stephen looked tense and slightly anxious.

I expected a quiet, reserved man who would want to shoot his scenes and leave, but when Johnny arrived it became clear that this wasn't the case.

He was very relaxed and down to earth, making time for photos with the crew and my kids who were there to meet Captain Jack.

The last shot of that day involved me sitting 'in' a toilet bowl while Johnny Depp described the scene into a dictaphone as if I was Rumpelstiltskin.

As the crew were setting up, Ricky was helping (actually stuffing) me into the toilet, as Johnny looked on.

It was at this point, I had an out-of-body experience.

In my mind's eye, I looked at the surreal scene - I'm hanging out, literally 'in' a toilet, with Ricky Gervais and Johnny Depp.

I pondered, does this mean my career is going well or not?

Some of most fun I had was doing the physical stuff, the slapstick. This was my nod to those childhood heroes of mine.

Fortunately, as a youngster, I had attended a theatre workshop one summer. I was taught stage fighting and acrobatics.

I knew how to take a hit and fall without getting hurt. I say without getting hurt, which was true at the age of 10, but at 41, falling out of a car or from a bookshelf take after take is not quite so painless.

So here we are, three years since its conception and Life's Too Short is finished.

What would my comedy heroes make of my efforts? Was that fall worthy of Oliver Hardy? Was that look to camera on par with David Brent?

I guess you'll be the judge of that.

Warwick Davis plays the lead role in Life's Too Short.
