“The Little Mermaid”: Boats, Trains and Automobiles

One of the biggest challenges on The Little Mermaid was the amount of material set in moving vehicles at night. Over the course of the story, the heroes travel in two different trains, a pick-up truck and a riverboat, and I knew that lighting large stretches of railway, road or river wasn’t going to be practical on our budget. Ultimately much of it ended up being done against green screen, with the notable exception of the riverboat, the first mode of transport to go before the cameras. Here are the relevant extracts from my diary.

 

Day 14

Today’s a big day because we’re shooting on a riverboat which has been hired at great expense. We have a huge amount of material to cover and there’s no way we can come back to the boat later if we don’t get it all. Chris and I make a game plan in the afternoon and arrive at the dock in good time.

It feels a lot like a micro-budget movie, shooting on a location that perhaps should have been a set (once we set sail you can’t see anything in the background because it’s night) with a tiny lighting package running off a little genny: some Kinos, two LED panels, and a 1K baby. Out there in the dark river, it is eery watching unfathomably huge container ships pass 50ft from us. We leave ‘B’ camera on the shore and try to co-ordinate with them by walkie as they shoot wide shots of the boat and we try to hide!

 

Day 16

Night driving scenes in a pick-up truck today. Poor Man’s Process was considered for these, then doing it for real with a low loader (called a process trailer here in the States). But at last green screen was chosen as the way to go.

The period vehicle is wheeled into our studio and parked in front of two 12×12 green screens, which VFX supervisor Rich dots with red tape crosses for tracking markers. Throughout the night he moves them around to make sure there are always a couple in shot. We light the green screen with two Image 80s (4ft 8-bank Kino Flos with integral ballasts) fitted with special chroma green tubes. Rich tells me to expose the screen at key, which in this case is T4.

Captain Dan Xeller, best boy electric, has lit car stuff before, so I give him free reign to establish the ambient level. He does it with 1Ks fired into 8×4 bounce boards, so that any reflections in the car’s bodywork will be large and sky-like, not strips like Kino Flos or points like pars or fresnels.

For shape we add a 5K with a chimera at a three-quarter angle, and a side-on par can with a “branch-a-loris” in front of it. Key grip Jason Batey designs this rig, consisting of two branches on a pivot like a Catherine Wheel, which can be spun at any speed by one of the grips, to simulate movement of the car.

Finally I add a 2K poking over the top of the green screen with Steel Blue gel, as a gratuitous hair-light.

Most of the night’s work is handheld, often with two cameras, but we also get some dolly shots, moving towards or away from the car, again to simulate movement.

 

Day 17

More green screen work today. At the end of the night we recreate one of the scenes from the boat with a piece of railing against the green screen. I do exactly the same lighting as before – Steel Blue three-quarter backlight, and a tungsten key bounced off polyboard. I love the way the actors’ skin looks under this light. Tungsten bounced off polyboard may just be the best light source ever.

 

Day 18

Stage scenes on real sets today, one of which is meant to be on the riverboat. The grips come up with a gag where we shine moonlight through an off-camera window gobo, which they handbash back and forth to simulate the boat rocking. We end up dialling it down so it’s very subtle, but still adds a hint of movement.

We move to the caboose (guard’s van), one of the train carriage sets. A second branch-a-loris is constructed so that both windows on one side of the carriage can have the passing trees effect cutting up the hard fresnel “moonlight”. We light from the other side with Kinos, and add a 1K baby bounced off foamcore to represent light from a practical oil lamp. Later the dialogue transitions to a fight scene, and we replace the bounced baby with an LED panel so it’s a little easier to move around and keep out of shot. I get to do some energetic handheld camerawork following the action, which is always fun.

 

Day 27

Interiors on stage, followed by night exteriors out the back of the studio. One of these is a shot of the heroes running, supposedly towards the train. It’s shot from the back of the 1st AD’s pick-up truck as we drive next to them. We have no condor today so the 12K backlight is just on a roadrunner stand, flooding out across the marsh between the lamp and the talent. With smoke it looks great, but lens flare keeps creeping in because the lamp’s not high enough.

We also shoot some Poor Man’s Process around a small set of the rear of a train car. Two lamps with branch-a-lorises in front of them, wind, smoke and shaky cameras help sell the movement.

Later we have a POV shot of a train screeching to a stop in front of the villain. The camera is on a dolly and the G&E team mount a 2K on there as well, to represent the train’s headlight.

Next week I’ll turn my attention to The Little Mermaid‘s smaller scenes, and discuss how the principle of lighting from the back was applied to them. Meanwhile, if you’re interested in some techniques for shooting in genuinely-moving vehicles, check out my blog from week three of Above the Clouds where we shot on Longcross Studios’ test track, and my article “Int. Car – Moving”.
